Question

why every celestial entity in the universe are appears only spherical why not any other shape like Cube and Cone Or any other shape???

Answer 1

Answer:

Celestial bodies are spherical in shape because of gravity. Whenever enough mass gathers close together, the resultant gravity, which follows the inverse square law, pulls equally in all directions and results in a spherical shape.

Explanation:

As gravity pulls matter towards other matter, a sphere forms. Why? Only a sphere allows every point on its surface to have the same distance from the centre, so that no part of the object can further 'fall' toward its centre. Gravity just keeps on pulling.
