Why is jupiter more oblate than earth?

Why is Jupiter more oblate than Earth? Jupiter rotates rapidly and is not as rigid as Earth because it has a liquid interior. What determines which cloud layers are found at which altitudes in Jupiter's and Saturn's atmospheres? Temperature Why or why not? It rotates rapidlyand is made predominately (【【) of gasso it not rigid (硬硬硬硬). These two reasons are why Jupiter is oblate, Saturnis even more oblate. Since the Jovian planetsare not rigid they will be oblate if they rotate rapidly

Get solution Why is Jupiter more oblate than Earth? because its outer layers are not solid and it rotates quickly. Jupiter is more oblate than Earth. Would you expect the other Jovian planets to be more oblate than Earth as well? Yes. None of them are solid and they all rotate quickly Also like Earth, Jupiter's shape is that of an oblate spheroid. In fact, Jupiter's polar flattening is greater than that of Earth's - 0.06487 ± 0.00015 compared to 0.00335. This is due to Jupiter's..

Jupiter rotates rapidly and is not as rigid as Earth because it has a liquid interior Jupiter is oblate because it is made of non-solid materials, has a large diameter, and rotates rapidly. Material at the equator must rotate more quickly than at the poles. All jovian planets, generally, have these properties and thus should be oblate. Why is Jupiter more oblate than Earth Because it is less dense than Jupiter, Saturn is more oblate than Jupiter, even though it rotates slightly more slowly. True Saturn has several enduring major storm systems similar to Jupiter's Great Red Spot

Incidentally, as I said, Saturn is more oblate than Jupiter, even though it's smaller and spins a touch more slowly. Why? Because its gravity is lower than Jupiter's! At the cloud tops, its gravity is only just a bit higher than Earth's, or half of Jupiter's. But at Saturn's equator, the centrifugal force is about 1/6 th Earth's. The magnetic fieldof Jupiter is 19,000 times stronger than the Earth's magnetic field. field is too strong. The origin of Jupiter (and other Jovian planets) strong magnetic field is the metallic hydrogen shell that surrounds Jupiter's rocky core. Metal is an excellent conductor o The Great Red Spot, a swirling oval of clouds twice as wide as Earth, has been observed on Jupiter for more than 300 years and is a persistent high-pressure region in the atmosphere. The Great Red Spot is located 22 degrees south of Jupiter's equator and produces wind-speeds up to 432 km/h (268 mph)

  1. The Earth has a rather slight equatorial bulge: it is about 43 km (27 mi) wider at the equator than pole-to-pole, a difference which is close to 1/300 of the diameter. If the Earth were scaled down to a globe with diameter of 1 meter at the equator, that difference would be only 3 millimeters. While too small to notice visually, that difference is still more than twice the largest deviations.
  2. Jupiter is an extremely massive planet, so much so that its mass is three hundred and eighteen times more than the mass of the Earth. Therefore, due to the sheer mass of Jupiter, anything that passes near the planet will either be flung right out of the solar system, torn apart by the gravitational tides or will be captured in the planet's orbit
  3. As noted in other's answers, Jupiter's shape is oblate or if you like, a flattened or squashed sphere. An Oval is not as precise a mathematical term, it's defined as a non circular closed shape, kind of like an egg. A squashed sphere or oblate sph..
  4. The same reason why the Earth is oblate: its rotation. The thing is that Saturn is so much larger, so much massive, yet rotates every ten and a half hour. Since angular momentum is proportional to angular velocity, Saturn is way more oblate than E..
  5. Why is Jupiter more oblate than Earth? Because its outer layers are not solid. • Because it rotates quickly. Would you expect the other Jovian planets to be more oblate than Earth as well? Yes. None of them are solid and they all rotate quickly..
  6. Earth and Mars spin a little faster, so they are about 0.3 percent and 0.6 percent thicker at the equator than the poles, respectively. This shape is called an oblate spheroid

Planetary Rotation of Jupiter, Saturn, and the Earth Jupiter and Saturn rotate far more rapidly than they logically should! Their extensive and thick atmospheres experience substantial turbulence due to those planets' very rapid rotation. This turbulence must necessarily convert some kinetic energy of rotation into frictional heat CH. 12 Explain why Saturn is more oblate than Jupiter, even though Saturn rotates more slowly. Even though Saturn rotates a little slower than Jupiter does, Saturn has less mass, and therefore less gravity to pull its material inward. Hence, Saturn's rotation should cause material at its equator to bulge outward more than on Jupiter, giving Saturn a greater oblateness Most of Jupiter is in the form of liquid metallic hydrogen. And underneath it all is a relatively small core of molten rock and ice. This relatively little core is up to twelve times heavier than the Earth. Theoretical considerations suggest that Jupiter's hydrogen probably accumulated around such a massive, pre-existing central object

Review Questions - chapter 23 1 Why is Jupiter more oblate

  1. Hydrogen/helium more compressible than rock, iron. Less massive planet, lower gravity, lower density. Surface gravity about 1/3 Jupiter, similar 11-hour rotation period. Less gravity, same rotation speed, so even more oblate (flattened). Atmospheric structure similar to Jupiter, but less visually dramatic
  2. A year, however, is much longer — Jupiter orbits the sun every 11.8 Earth years. What's more, due to this rapid rotation, the planet has an oblate shape with flattened poles and a bulging equator
  3. Its oblate shape is apparent even in a small telescope. Even though Saturn rotates slightly slower than Jupiter, it is more oblate because its rotational acceleration cancels a larger fraction of the planet's gravity at the equator. The equatorial gravity of the planet, 896 cm (29.4 feet) per second per second, is only 74 percent of its polar.

Jupiter Compared to Earth - Universe Toda

Density, mass and volume. Known as a gas giant, Jupiter is composed primarily of hydrogen and helium. It weighs in at 1.9 x 10 27 kilograms. Although it is significantly more massive than Earth. In contrast, an oblate planet produces an extra force that tugs the moving object toward its equatorial bulge, and also toward any internal core. When combined with the known mass, volume and rotation rate of Jupiter, observations of these effects indicate that Jupiter has a dense core containing up to 12 Earth masses

One side of Earth is closer to the Moon than the other side, by a distance equal to Earth's diameter. Hence, the gravitational force is greater on the near side than on the far side. The magnitude at the center of Earth is between these values. This is why a tidal bulge appears on both sides of Earth The mathematician and astronomer assigned these coordinates to more than 8000 places across the known world.

The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis. Who discovered Earth? Five planets have been known since ancient times — Mercury, Venus, Mars, Jupiter, and Saturn Uranus' atmosphere:. Since Uranus lies more than 19 AU from the Sun, it receives 360 times less light and heat from the Sun than Earth. As a result, its atmosphere is extremely cold, with a temperature of about -214C at the 1 bar pressure level (equivalent to the average air pressure at sea level on Earth) Saturn is the only planet less dense than water (0.7 gm/cc, i.e. it would float). Saturn's hazy yellow hue is marked by broad atmospheric banding similar to, but fainter than, that found on Jupiter. One of the more obvious features is Saturn's ring system. Inclined at 27 degrees, the rings can be seen at various angles during Saturn's year Earth's Shape. Earth is a sphere or, more correctly, an oblate spheroid, which is a sphere that is a bit squished down at the poles and bulges a bit at the equator. Or to be more technical, the minor axis (the diameter through the poles) is smaller than the major axis (the diameter through the equator). Half of the sphere is a hemisphere.

The Earth in the Solar System. The Earth is the third planet from the Sun, located between Venus and Mars, 93 million miles from the Sun It is one of the Inner or Terrestrial Planets. These planets include: Mercury, Venus, Earth and Mars. The remaining planets; Jupiter, Saturn, Uranus and Neptune; are called the Outer or Jovian Planets And Earth's bulge is about 1:300 (0.33%}; if you look at pictures of Earth taken from space, it looks pretty damn spherical. the bigger and softer the planet and the faster its spin, the less spherical it looks, so some of the gas giants (Uranus, Neptune, Jupiter, and especially Saturn) are spinning fast enough to show a bulge

Bad Astronomy Hey, flat Earthers! You chose the wrong

  1. Saturn is visible in the sky now, a beautiful ringed world with a density so low it would float in water. Wait. No. That's actually wrong, says Wired Science blogger Rhett Allain
  2. Earth is an example of this, hence the oblate spheroid shape. Jupiter is the fastest spinning planet in our solar system and therefore is more flattened than Earth
  3. Jupiter is significantly oblate (0.065), and its estimated moment of inertia ratio {C/MR2e) of 0.264 indicates a significant concentration of mass towards the center of the planet. Saturn is even more oblate (0.098) and in fact is the most oblate body in the solar system
  4. If the casual reader comes across just the oblate shape corresponds to a higher gravitational potential energy as compared to a perfect sphere, then he'll wonder why the Earth (and Jupiter, Saturn, etc.) don't relax to the spherical shape from their current oblate shape, since there is potential energy awaiting release

Galilean moons any moon that appears more than half lighted but less than dull The earth speeding up slightly is thought to be because human activity (mostly, dam construction) has redistributed some of its water toward the poles (and so, toward the axis of rotation). However, the melting polar ice will eventually more than offset this, and the net effect of human industry is likely to be a slowdown

Earth is the third planet from the Sun. It is the largest planet of the inner Solar system, bigger than Mercury, Venus and Mars. It is the only planet that support life and also the most beautiful planet Jupiter is an unusual planet by terrestrial standards, both in size and composition. Only slightly denser than water, Jupiter is 317.8 times more massive than Earth. Secondary only to the Sun itself, the giant planet dominates the Solar System (Figure 1-3) Regarding Jupiter Jupiter is noticeably oblate, why? Voyager 1 and 2 made major discoveries, like what?

Oblateness = 0 means the object is spherical (like Venus), and oblateness = 1 means it is a straight line. Astronomers can infer the chemical make up of a planet simply by knowing its density and comparing it to the known density of compounds here on Earth If the planet is spinning then it will also bulge at the equator and be an 'oblate spheroid'. The Earth is 21km fatter at the equator than at the pole. Matt Ford, Wellington, New Zealan Jupiter has 317.8 times the mass of the Earth. Even though Jupiter is an enormous, massive planet, it's much smaller than the Sun. The Sun accounts for 99.86% of the mass of the Solar System

But it's very hard to say who was the first to discover that the Earth is an oblate spheroid (more or less) is given that so many people contributed to this discovery. This, by the way, is how modern science works. Most modern scientific discoveries are team efforts. Galileo devoted a lot of time to studying Jupiter and Saturn, and if he. See 7 Jaw-Dropping New Photos Of Jupiter Taken This Week By NASA's Juno. This article is more than 2 years old. but Earth is actually an oblate spheroid, pockmarked with mountains and. Explain why Saturn is more oblate than Jupiter, even though Saturn rotates more slowly. What observations of Saturn's rings proved that they are not solid? The Space Shuttle and other spacecraft orbit the Earth well within the Earth's Roche limit. Explain why these spacecraft are not torn apart by tidal forces The shape of Jupiter is actually an oblate spheroid. An oblate spheroid has flattened poles and a bulging equator. Jupiter has a more irregular shape than Earth due to its greater mass and.

This speed gives Jupiter an oblate spheroid shape and it rotates so fast that it completes one rotation in less than 10 Earth hours, means one day on Jupiter is equal to 10 hours. However, it is far away from Sun being the fifth planet in the solar system, and it takes 11.86 Earth years to complete one revolution around the host star (1) Mass in M ⊕, the unit of mass equal to that of Earth (5.97 × 10 24 kg).

•IR: Jupiter radiates about 2.5 times more energy than it receives from the Sun. •Jupiter must still be getting rid of its heat of formation •This internal heat helps power Jupiter's weather. By contrast, the weather on the Earth, Venus, and Mars is powered by solar energy, as the internal geothermal heat is insignificant compared to. The gravity of Jupiter's mass ought to have pulled the planet into a perfect sphere. However, Jupiter rotates very quickly, and the equatorial mass is lifted from its natural altitude by the. When compared to Jupiter, Earth is only a dwarf; however, it is considered less dense than our terrestrial planet. Jupiter's size can hold 1,321 earths in total. The size and mass of Jupiter is said to be proportionate because in case Jupiter had more mass, the planet would shrink quickly Jupiter rotates in just under 10 hours and has an equatorial radius about 11 times that of Earth, creating a much stronger centrifugal force. As a result, in spite of a surface gravity 2.64 times stronger than Earth's, Jupiter is much more oblate, by about 6.5% Why Jupiter is not a rocky planet? It may also have a rocky core of heavier elements, but like the other giant planets , Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator)

Jupiter is an oblate spheroid and has a slight bulge around its equator. Jupiter is more than twice as massive as all the other planets in the solar system combined and its mass is 318 times more than that of Earth. Jupiter radiates more energy in to space than it receives from the sun and the interior of the planet is very hot with. Jupiter experiences the shortest day than any planet in the solar system. It spins on its own axis once each 9 hours and 55 minutes. The fast rotation tends to flatten Jupiter a little bit, providing it an oblate shape. Fact 4. Jupiter takes 11.86 Earth years to orbit the sun. This implies that when seen from Earth, Jupiter appears to move slowly

Why does Jupiter have so many moons? - Qrie

But because Earth is so much more massive than you, your force doesn't really have an effect on our planet. Gravity in our universe. Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers.

Saturn is more oblate than Jupiter, which means a) it has a larger mantle and smaller core b) it has a smaller mantle and smaller core c) it has a smaller mantle and larger core d) it has a larger mantle and larger core e) none of the a a) it has a larger mantle and smaller core Shepherd moons a) confine the ring particles b) interchange orbit Technically speaking, it's an oblate spheroid — a sphere that's been squashed, such that the distance from Earth's center to sea level is about 13 miles greater at the equator than at its poles. According to the esteemed font of scholarly knowledge known as, Wikipedia, the Earth is an oblate spheroid. However, according to the Flat Earth Society who have the word Earth right there in their name, the Globe is actually a big flat disk, gravity is a lie and NASA is the most powerful commercial entity on Earth, which we think sounds a lot more likely than all of that science.

Why is Saturn oblate? - Quor

  1. Earth is the fifth-largest planet in the solar system. It's smaller than the four gas giants — Jupiter, Saturn, Uranus and Neptune — but larger than the three other rocky planets, Mercury, Mars and Venus. Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is mostly round because gravity generally pulls matter into a ball
  2. read more: Even planets have a (size) limit. As a result, the perfect sphere expected in hydrostatic equilibrium shifts to the so-called oblate spheroid. In this case, the object is wider than the pole at the equator. This also applies to the rotating Earth with an equator diameter of 12,756 km and an interpole diameter of 12,712 km
  3. Discoveries of Jupiter's atmosphere by Galileo Probe: • first observations of ammonia clouds. • lightening charges in Jupiter's atmosphere • more heavy elements than in the Sun • missing water • abundant noble gas Lightening on Jupiter Galileo was launched in 1989. The Probe was released t
  4. Jupiter is the largest planet in the Solar System, it's no surprise. But the definition does not really do justice to this. For one, Jupiter's mass is 318 times as massive as the Earth. In fact, Jupiter is 2.5 times more massive than all other planets together inside the Solar System
  5. Solar System Extremes. Jupiter. All the other planets in our Solar System could fit inside Jupiter. Pluto, a dwarf planet, which is smaller than many moons, including our moon . Venus is about 95% of the Earth's diameter and 82% of the Earth's mass. Jupiter. A 100-pound person would weigh 254 pounds on Jupiter. Pluto
  6. The Cassini spacecraft reveals the cratered surface of Mimas, a moon whose shape is flattened at the poles. See Not Quite Round to learn more about why the moon has this oblate shape. This view looks toward the trailing hemisphere of Mimas (396 kilometers, or 246 miles across). North on Mimas is up and rotated 1 degree to the left. The image was taken in visible green light with the Cassini.

Why is Mars reddish in color? ! What was the result of Viking's search for life? ! What are the factors that determine how rapidly a planet loses its atmosphere? ! Which planets have rings? ! Why did Venus and Mars evolve differently than Earth? ! Why is Jupiter noticeably oblate? ! Why does Jupiter emit more energy than it absorbs radius of Earth! Saturn is thus said to be quite oblate: the greater the difference between the polar and equatorial distances, the more oblate is the shape of the planet. Saturn spins around its polar axis much faster than Earth does. Though it is much larger than Earth, Saturn rotates once in 10 hours 39 min-utes, over twice as fast as Earth. Being the largest planet in the solar system, Jupiter boasts a radius more than 10 times Earth's, at nearly 70,000km. The counter-rotating winds in the zones and belts reach speeds of 100 metres. Why is the earth not perfectly sphere? The Earth is not a perfect sphere. Because it is spinning, it bulges at the middle. This makes the Earth a squished sphere, or oblate spheroid. Datums include an approximation of this spheroid. Which area on Earth receives more light? The equator. Is Earth the 5th largest planet
