Gravity.

Gravity pulls things together equally in all directions. This means that once the amount of material collected together gets big enough to it flows into a sphere. However, if the sphere is rotating then the speed of the spin want to fling material out and this means that spinning bodies are not spheres but 'oblate spheroids', they are fatter round their middles.

Stars and planets are spherical due to gravity. Gravity pulls all particles towards the center of mass, causing them to be compacted into a spherical shape. This balance between gravity's inward pull and pressure from within helps maintain a spherical equilibrium.

Why stars are in the shape of a star?

They are not star-shaped. Stars are actually spherical due to gravity.


Are stars shaped like spheres?

Yes, stars are shaped like spheres (same with planets and moons).

Bot stars and planets are spherical objects that are held together by gravity.


If the sun is a star why isn it shaped like one?

Stars are not physically star-shaped (as in having 5 points). They're spherical in shape.


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.


Who is euclid in the field of astronomy?

He is the father of spherical astronomy, by which the location of objects like planets and stars in the universe can be determined.


What shape do you think the universe is?

Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.


Why do stars wobble?

Stars wobble due to the gravitational influence of the planets orbiting them. As planets orbit their stars, their gravitational pull causes the stars to move slightly in response. Scientists can detect this wobble in a star's position, which provides information about the planets orbiting it.


Are all planets and stars shape like circle?

All planets and stars are approximately spherical in shape, a shape formed under their own gravity. Most are `oblate` spheroids though, squashed spheres, since their rotation can cause them to `bulge` out at the equator if it is sufficient enough.


Do stars orbit planets or planets orbit stars?

Planets orbit stars.
