Question

Why are the panets in our sola system round?

Answer 1

mmk, they are not nesseccarily all round, they look round from a distance but they have deforms like craters and mountains etc. and

XxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxXxX

and gav mel 25 no you wouldnt, the world has gravity and if you go to jump of the edge it would pull you back, and yea...

Answer 2

Never mind WHY, I'd like to know WHAT the PANETS are .

Answer 3

Because if they were square you would fall off the edge of them.

Answer 4

because square ones don't spin good.

Answer 5

Planets (...and also stars) form within immense drifting clouds of gas and dust. Every bit of gas and dust generates a tiny gravitational force. In relatively dense regions of the drifting cloud (...called a 'nebula') two or more bits of gas or dust may be close enough so that they're attracted to each other by their gravity. They clump together, which increases their overall gravity. This larger clump is surrounded by more bits and pieces which are drawn in from all directions. The original clump grows in size and produces more gravity, which in turn pulls in even more material from all directions. The result is a growing sphere.

Answer 6

What is a panet?

Answer 7

They are not round, they are spherical, because of gravity which pulls from all directions equally (apart from minor surface bumps like mountains and Valleys which are caused by plate tectonics).

Round is a 2 dimensional description, a sphere is 3 dimensional one.

Answer 8

Everything on a planet is pulled towards the center by gravity.  Everything is trying to get as close as possible to the center.  The only shape that gets everything as close as possible is a sphere.  If the planet were a cube the corners would get pulled down till you had a sphere.

Smaller objects (such as asteroids) do not exhibit this because their gravitational pull is not near sufficient to cause this to happen.

Answer 9

I Know that we have planets in our solar system but panets are new to me! Can you give us more info on these panets. The planets in the solar system are not really round as such but are spherical and tend to fluctuate very slightly and are this shape due to gravity and solar winds.

Answer 10

It's because of the gravitational force. Although we do not yet know that well how planets are formed (whereas we know pretty well how stars are formed), it seems that Earth, and other planets, go through a liquid phase during their formation, and gradually cool and then become solid. Anyways, during the time when they are liquid, the gravitational force pulls them into a spherical shape, because it can be proven mathematically that the sphere is the shape for which all of the mass is as close to the centre of mass as possible. That is, if you're given any other shape, you can re-form it into a sphere and lower its gravitational self-energy.

Answer 11

I don't know what panets or sola is....
