Two actually. There are two forces acting on stars. One is the outward force from the immense power of nuclear fusion. When atoms are fused or split an incredible amount of power is released (which is why we use fission for power, fusion needs extreme temperature to happen). The outward forfce of fusion wants the star to expand to release the energy. However, gravity doesn't agree. The force of gravity wants to pressure the star until it collapses. Thus, these two forces hold each other in a deadlock for milions of years. Of course, the star will eventually run out of resources and gravity will prevail as always.

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.
How do stars keep their spherical shape?
Gravitational Force
What attractive force keeps planets in orbit around stars?
Gravity.
How stars get their shape?
The drawn shape of a star is based on astrological observations from Earth. The actual shape of a star in space is a blazing sphere of super-heated gases.
Why there is a definite shape for stars and as sphere for sun though they all belong to star family?
marsarauss it it 20,000,000light year away
What type of force is mainly responsible for giving celestial object there round shape and keeping them in the shape?
The force mainly responsible for giving celestial objects their round shape and keeping them in that shape is gravity. Gravity pulls mass inward toward the center, resulting in a spherical or nearly spherical shape for large celestial bodies such as planets, stars, and moons.
What force gives planets stars solar system their shape?
gravity of course
What shape are star?
Stars are spherical in shape. They are balls of hot gas. If a star is spinning fast enough, it will bulge a bit around the middle, but it will still be pretty close to a sphere.
If the sun is called a star why is it the shape of a sphere?
A star that shows arms radiating outwards are a graphic representation of a star. Graphically, a star may be shown with 4, 5, 6, etc, arms. The same is for our sun, which is often drawn with lines representing radiation of sunlight coming from it.
