they are not circle i know but they have a shape like egg. Even scientist do not this answer. Bytheway you guys say what you think about the question.
THANKS

Planets formed from junk congregating together. It was very hot and loose and melty and working in free fall. In such a situation, substances try to form surfaces with the least surface area. That's a sphere.
I'm not sure why you say that scientists don't know the answer to this. This is well established.

I agree with Heinz M. except the centrifugal force part. Sorry my physics teacher likes to rant and say there is no such thing as a centrifugal force, it's just inertia trying to keep a rotating object moving in a straight line but a gravitational force pulls it inward, altering the course. Or like in the bucket of water situation, the water wants to keep going straight but the force from the bucket pulls the water and makes it go in a circle, that's why when you let go of the bucket it moves in a straight line tangent to the circle, not straight away from the center. But this wasn't a physics question... i agree with Heinz M. Something like gravity pulls the particles together forming a mostly spherical shape with a little bit of budging due to rotation

Gravity pulls high parts of the planet down to the lower part. This hap pends until all things evened out.
In smaller asteroids the gravity is not enough to round it off.
It should be noted that the earth is so flat, that if you take the difference of the highest point on earth and the lowest is 19 kilometers.
If the surface area of the earth was reduced to the size of an 8.5 by 11 piece of copy paper, this difference would reduce to 3.7 millionths of an inch. This is smoother than a mirror.

they do no longer look to be. Planets are around (like a ball). A circle is a "flat", 2-dimensional merchandise. the reason they're around is via the fact gravity acts the two in all instructions, pulling the debris of the planet the two in the direction of the centre

Actually the planets are close to perfect balls due to the equal attraction of all the matter towards the center of their mass. With rotation one usually observes a bulging at the equator, due to the centrifugal forces. ~
About the question, it has been asked here many times before.

When planets and suns form, they are molten. In this molten state with no gravity influencing it, it will take a state of equilibrium. This cause it to take the smallest volume and it becomes round. Have you ever try this? Try flicking some water droplets in the air. You will notice they become round in mid air. Why? Because in this state of free fall, they clump together in the smallest state to become round.
