Gravity is the force that makes the Sun and planets roughly spherical in shape. Their rotation, if fast enough, will cause their equators to bulge and their poles to be somewhat flattened.
The sphere is the perfect shape in nature for all fluids. Any body of fluid acted upon only by its own gravity will assume the shape of a sphere, where every point on the surface is equidistant from the center of gravity.
Objects in the solar system are composed of gas, ice, and rock. If they are large enough, they reach "hydrostatic equilibrium" in which their matter is forced together by gravity into a spherical or ellipsoid shape.

JordanThe Sun maintains its shape and structure due to a balance of two forces: gravity, which pulls mass inward, and the pressure of nuclear fusion at its core, which pushes outward. These forces work together to keep the Sun stable and prevent it from collapsing under its own gravity.

How does the sun keep its size and shape?
The sun maintains its size and shape through a balance of forces. Gravity pulls inward, trying to collapse it, while nuclear fusion at its core generates energy that pushes outward. These two opposing forces create an equilibrium that sustains the sun's size and shape.
What is the shape of the moon when it is opposite to the sun?
The Moon of the Earth has a spherical shape regardless to its position compared to the Sun.
What shape is the sun's core?
The Sun's core is mostly spherical in shape. It is where nuclear fusion occurs, producing energy in the form of light and heat.
What can change shape and get light from the sun?
Clouds can change shape and get light from the sun when they pass in front of it, causing shadows to form on the ground.
What is the shape of the path of a planet or asteroid around the sun called?
The path itself is called its orbit. The shape is an ellipse, with the sun sitting at one of the foci.
