Planets are round because they are bond together by gravity. Picture a planet as a bunch of rocks floating in space. Those rocks will be attracted to each other by gravity and in the same way a rock rolls down a hill to the lowest spot, it will for a sphere.

∙ 16y agoit's the same as saying why is the earth round? well all i can say is that it's the way things are. you don't see square or pentagonal or hexagonal craters do you. if different shapes of craters are found then we would have to review our knowledge of physics.
Although many craters are round, not all are. There are scalloped craters, square ones, oblong ones as well as stretched out looking craters. It's all about the angle of impact. Perpendicular impacts are rare. The average impact angle is approximately 45 degrees. The impact angle is small except when the angle is shallow (less than 20 degrees.) When the impact angle is less that 10 degrees the crater is distorted by a great deal. Some craters are large enough and instead of simply being bowl shaped the interior structure (central peak or peak ring) and outside the crater the debris is thrown out of the impact crater causing different shapes and sizes.

Can dwarf planets be any shape except round?
No planet known to man is a perfect sphere (also that I know) so dwarf planets can definitely be any shape
Are dwarf planets any shape except for round?
No. Part of the definition of a dwarf planet is that it is large enough for gravity to pull it into a round shape. They may be a tiny bit oval shaped, but basically round.
Why are the earth and other large planets round?
Not all Planets are round. Some dwarf planets are not roundRound is a good shape. The force of gravity collapses matter into a spherical shape, once there is enough of it. Small bodies of normal solid matter less than a hundred miles across lack sufficient mass to pull them into a spherical shape.
Which planet is nearly round in shape?
All planets in our solar system are somewhat squished in shape due to their rotation, or are "oblate spheroids" - but Venus is the least oblate or the most spherical, owing to its slow rotation.
What is the only planet that is not spherical in shape?
All planets are 'round' because of gravity. With the formation of the Solar System, gravity gathered gas and dust into clumps which became larger and eventually planets. The collision of these pieces caused planets to become hot and molten and gravity pulled the molten material towards the planet's centre in the shape of a sphere. The planets cooled and remained spherical
Is Mars round?
The planet Mars is round in shape. All of the planets in our solar system are orbits. The gravitational pull of the sun has formed the planets to be around.
Which of the following is true for both gas planets and terrestrial planets?
They are a round shape.
Why are all the planets round in shape?
When the Earth rotates from west to east, it produces wind in east to west direction and because of this friction occurs in between them which has turned the Earth round in shape.
Are all-stars round?
Yes. All the stars are round and all the planets are round.
Are all stars round?
Yes. All the stars are round and all the planets are round.
What is the typiccall shape of the planets?
Planets are all spherical.
What are the characterstics of Planets?
all planets have a circular shape
Why are most fruits round in shape?
Most fruits are round because God made them that way. It's the same reason why all planets are round. Being round in shape, they are easy to hold and eat Baseballs, soccer balls, tennis balls, etc., are round because it's the perfect shape for holding in our hands. Fruits are also round because they look cute that way.

What is the brief description of all the planets?
