What planet has a perfect sphere shape?

Mercury and Venus are the most elongated of the planets. Like marbles, they are virtually perfect spheres. Some planets, however, are not completely spherical. Saturn and Jupiter are somewhat thicker in the center. Mars is thinner at its equator than at its poles.

In order to be perfectly spherical, a planet would have to be made of soft material like rubber or foam with no hard parts such as rocks inside it. The only other known planet that might be described as having a perfect sphere shape is Uranus. It is also not completely round but has two shapes: elliptical and egg-shaped.

The three planets closest to the Sun are mostly spheres covered by clouds and ice. These are Mercury, Venus, and Earth.

Moons tend to be less spherical than their planets because they are affected by tidal forces from their planets. The more mass there is near the center of the moon, the more rapidly it will rotate. This means that the low-mass part of the moon will be stretched out like a drumhead when it rotates, which can make it bulge out where the tension is highest.

The solar system's biggest spheroid is probably Jupiter. It is nearly 10 times as massive as Earth and spans about 30 times our radius.

Are planets perfectly spherical?

All of the planets are circular due to gravity. Gravity drew this molten material inwards towards the planet's center, forming it into a spherical. When the planets cooled, they remained spherical. Because planets rotate, they are not completely spherical. However, because the force of gravity is the same on all points on a rotating body, it follows that a spheroid (a shape composed of spheres) would be an accurate representation of a rotating planet.

The fact that planets seem to be spheres to our eyes has to do with how light travels within them. You can think of light as water waves; as these waves travel through the planet, they encounter less and less resistance until they reach the opposite side where they spread out again. This means that from down here on Earth, objects near the surface look like they're closer together than they actually are. Objects far away look like they're farther apart than they really are. This is why stars appear to be spheres when viewed from Earth-they're actually balls of hot gas.

Planets also appear to be spheres because there are no major differences in height across their surfaces. If there were such differences, then sunlight falling on one part of the planet would have to pass through more or less air than if it was falling on another part, which would cause temperatures to vary across the planet.

What would have to happen in order for Earth to become a perfect sphere?

The quick explanation is that gravity causes a planet to be spherical. Gravity pulls evenly from all sides of a globe. Gravity pushes from the center outward, much like the spokes of a bicycle wheel. This results in a planet's overall form being a sphere, which is a three-dimensional circle.

Spherical planets are common in science fiction. Scientists think that during planetary formation most of the mass of the planet was concentrated in a central ball and only later did it spread out to fill up its crust. The more massive a planet is the faster it will collapse under its own weight.

Earth is not exactly round, but close enough for government work. The last time Earth was completely covered with water was 5 million years ago, when Antarctica was part of South America. Most of North America and Europe were submerged as well.

Since then we've had a lot of fire and ice which has melted away the original rock layer underneath our feet, leaving a solid shell around any material particles that were still afloat. This is why you can walk on the moon even though it's far away from the sun: There's no air there to heat up like there is here on Earth. Instead, the moon is made of leftover debris from when stars were formed.

Over time the effect of gravity causes everything liquid to collect at the planet's middle.
