Shape. If not affected by external forces, all objects have a tendency to concentrate towards the center under the action of gravitational force. The most concentrated result is a spherical shape!
Although the star is solid on the surface, it is also deformable because the solid particles are also movable, which makes it possible to transform it into a spherical shape. <>
Stars on a summer night.
The activity of the energy inside the star makes the star irregularly shaped. However, the stones of a high mountain are rolled down from a high place by the gravitational pull of the stars (gravitational pull), and the rivers carry sediment from a high place to the low-lying ocean (the rivers also flow by the gravitational pull of the stars) are all examples of concentration towards the center, and they all make the stars turn from irregular to spherical. If the interior of the star ceases to move, it is possible that after many billions of years, the star will become a very standard spherical shape (except for centrifugal force and the gravitational pull of other celestial bodies).
Many asteroids, due to their own small mass, resulting in their own gravitational force is relatively small, and the star is generally composed of relatively hard solid rock, it is difficult to complete the process of moving to the center under the action of its own gravity, so their shape is strange, oval, rod-shaped. Many.

Stars have their own inward attraction and centrifugal force, and their appearance is macroscopically smooth, that is, close to the shape of a sphere, so stars have no edges and corners. The stars we see with the naked eye are rice or cross-shaped, which is caused by the scattering and refraction of the light emitted by the stars as they pass through the atmosphere, and the slight or relatively large scattering of the human eye itself.
