Why is Saturn most oblate planet?
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 gravity.
Why are Saturn and Jupiter oblate?
Why are Jupiter and Saturn so noticeably oblate in appearance? Jupiter and Saturn are so noticeably oblate because of their rapid rotation.
Why is Saturn flattened?
When seen through a telescope, Saturn is one of the most beautiful sights in the night sky. It looks like a big ball inside of rings. Saturn is a very large gas planet which spins very rapidly on its axis. It spins so fast that it flattens out the top and the bottom of the planet.
Why does Saturn rotate on its side?
This is the conclusion of recent work carried out by scientists from the CNRS, Sorbonne University and the University of Pisa, which shows that the current tilt of Saturn's rotation axis is caused by the migration of its satellites, and especially by that of its largest moon, Titan.
Why does Saturn appear as an oblate spheroid?
Saturn is a gas giant composed predominantly of hydrogen and helium. It lacks a definite surface though it may have a solid core. Saturn's rotation causes it to have the shape of an oblate spheroid that is it is flattened at the poles and bulges at its equator.
How does Saturn rotate?
Orbit and Rotation One day on Saturn takes only 10.7 hours (the time it takes for Saturn to rotate or spin around once), and Saturn makes a complete orbit around the Sun (a year in Saturnian time) in about 29.4 Earth years (10,756 Earth days).
Which planet is the least oblate?
This means that it is the least spherical; its equatorial diameter is larger than its polar diameter. This occurs because of its rapid rotational period: Saturn (which is about 9.5 times larger than Earth) rotates more than twice as fast as the Earth. The most spectacular feature of Saturn is the ring system.
Does it rain diamonds on Saturn?
About 10 million tons of diamond rain down on Saturn each year. The new molecule is relatively heavy, and when attracted by the planet's gravity, begins to be drawn downwards.
Which planet rotates the wrong way?
planet Venus Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.
Which planet rotates on its sides Why?
Uranus' axis is so tilted, it actually looks like the planet is rotating on its side.
Are all planets oblate spheroids?
None of the planets in our solar system are perfect spheres, nor for that matter is our sun. All those bodies could more accurately be described as "oblate spheroids." Objects with this shape bulge slightly around the middle.
Which planets are oblate spheroid?
Oblate spheroids The oblate spheroid is the approximate shape of rotating planets and other celestial bodies, including Earth, Saturn, Jupiter, and the quickly spinning star Altair.
Does Saturn spin faster than Earth?
Earth: 29.78 km/s (66,615 miles per hour), or a period of about 365.256365 days. Mars: 24.077 km/s (53,853 miles per hour), or a period of about 686.93 days. Jupiter: 13.07 km/s (29,236 miles per hour), or a period of about 11.86 years. Saturn: 9.69 km/s (21,675 miles per hour), or a period of about 29.42 years.
Why is Saturn the least spherical?
Saturn is the most oblate of the gaseous planets. This means that it is the least spherical; its equatorial diameter is larger than its polar diameter. This occurs because of its rapid rotational period: Saturn (which is about 9.5 times larger than Earth) rotates more than twice as fast as the Earth.
What happens if you touch Saturn’s ring?

What planet is full of diamonds?
For centuries, astronomers have been fascinated by Saturn. After all, she has been hailed as the precious jewel of our solar system, one of the most beautiful planets. And while her rings have mesmerised us for centuries, it is even more amazing to realise that it quite literally rains diamonds out there!
How did Venus turn upside down?
Venus also orbits the Sun anti-clockwise, but its unusual axis rotation is due to being upside down – it was knocked off its upright position earlier in its history! Astronomers believe that at some point, a colliding celestial body tilted Venus so far off its original position that it is now upside down.
What planet would float in water?
Saturn Saturn could float in water because it is mostly made of gas. (Earth is made of rocks and stuff.) It is very windy on Saturn.
Why does Uranus spin the wrong way?
Same as with Venus, Uranus also had counterclockwise rotation until a gigantic impact changed everything. The explanation for this is that in its formation history, Uranus collided with an Earth-sized object which lead to the change of its rotation.
How did Uranus get its tilt?
Orbit and Rotation Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. This unique tilt causes the most extreme seasons in the solar system.
Why is oblate spheroid?
Answers. The rotation of the earth causes the earth to swell more at the equator, compared to at the poles. When the earth rotates, there is a strong outward force on the earth matter near the equator. This force causes the swelling, and gives the earth the oblate spheroid shape.
Why are Jupiter and Saturn not perfectly spherical?
Why are Jupiter and Saturn not perfectly spherical? They rotate rapidly. Which of the giant planets was predicted to exist mathematically before it was ever seen through a telescope? If you could find a large enough ocean, which one of these planets would float in it?
What makes a planet oblate?
Its shape is an oblate spheroid. This just means that it flattens at the poles and widens out at the equator.” Earth bulges at the equator because of the centrifugal force during rotation. Like spinning a pizza, the mass pushes outwards and flattens out along the axis of rotation.
Why is Pluto no longer a planet?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
What is the slowest moving planet?
Venus is the slowest – it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. Sun is the nearest star. Planet with the slowest rotation: Venus.
Why are planets oblate spheroids?
The oblate spheroid shape is the result of two main factors: gravity and rotation.
What if Earth had 100 moons?

What would happen if Earth had two moons?
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.
Which planet is rich in gold?
Well, at current market prices, 16 Psyche contain enough gold and other precious metals to be worth roughly $700 quintillion, which is enough to give every single human being on this planet a private fortune of nearly a hundred billion bucks.
Is there gold on the moon?
Digging a little deeper than the Moon's crust, scientists have discovered that the Moon does indeed have a number of precious metals such as gold and silver.
