Are there not round planets

Answer 1

The large ones, bigger than say 400 kilometers in radius, are round because the amount of mass present produces such a strong gravitational field that most substances such as rock become very plastic. But, if the planet is too close to its sun, or if a satellite is too close to its parent planet, the shapes can be very out-of-round due to tidal effects. The above image is of the asteroid Vesta taken by the Hubble Space Telescope. It has a diameter of 525 kilometers and at this size you can see that large objects already have a noticeably round shape to them. The telescope photographed the asteroid while it was rotating and above you can see four of the views from the 'movie'

Answer 2

No Mars is not because it has craters all the way round it.

Edit: It also has high mountains. Even if it was smooth it's still not a perfect

sphere although it's quite close to being a sphere.

Answer 3

No. they are slightly smoother at the top ;

Answer 4

The planets that are closer to the sun can come in slightly different shapes but the planets far away from the sun are round.

Answer 5

no there not
