No planet is spherical, that would imply they are completely smooth. All Planets are roughly spherical because of the process of planetary formation. That is that asteroids group together under the influence of gravity, this cluster of asteroids would have its own gravitational field, and therefore attract more asteroids. More asteroids means more gravity, which means still more asteroids. So you get this runaway effect where more and more asteroids are being drawn together while the asteroids in the middle are starting to get squashed. Once you have a big enough ball of asteroids it becomes a good estimation to say 'It's roughly spherical'.
If the ball is massive enough it can even start pulling in the surrounding gasses, forming an atmosphere.
What else can I help you with?
What shape are planet?
The inner planets have a spherical shape. In fact all planets are more or less spherical.
Are planets different shapes?
No. All planets are spherical.
What is the typiccall shape of the planets?
Planets are all spherical.
What are inner planet shapes?
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
What is the shapes of all nine of our planets?
They are 8 major planets and 5 known dwarf planets. All are approximately spherical, and a better approximation is to consider them as oblate spheroids.
What is the planet Venus shaped like?
Venus is roughly spherical, as are all planets.
What are planets and stars?
Spherical
What doe s all the planets look like?
Most Planets seem spherical, but have lots of indentations. There are no common factors among planets and all appear to have physical differences
Are the sun and planets round?
Yes!!!! The correct term is "spherical", which means round in all dimensions like a ball. (A hoop is round, but is not spherical) Stars and planets are not perfect spheres, but they are very close to perfect spheres.
What shape are planets and stars?
Spherical
Why all planets are sphare?
The reason planets appear to be spherical is because gravity compresses the planet into a shape that most evenly distributes the gravitational force among the planet's mass. Therefore, it must become rounded, or spherical.
