why are stars shaped in a star form
All stars are spheres. Their own gravity forces then to take that shape
Stars may appear as spherical objects due to their own gravity. The force of gravity acts equally in all directions, pulling matter towards the center. This gravitational force causes stars to collapse inward, resulting in a spherical shape. However, it is essential to clarify that stars do not have a literal "star shape" with pointed tips like a geometric star.
To understand why stars form as spheres, you can consider the process of star formation. Stars begin their life in massive clouds of gas and dust called nebulae. Gravity causes these nebulae to contract and condense under their own weight. As more matter accumulates at the center of the nebula, it heats up and starts to glow, giving birth to a star.
During this gravitational collapse, the matter is uniformly attracted towards the center, resulting in a spherical shape. The gravitational force is isotropic, meaning it acts equally in all directions, causing material to collapse symmetrically around the central core of the forming star. As a result, stars generally take on a spherical shape, with the gravity balancing the forces pushing outward from the internal nuclear reactions.
While stars may appear as points of light from a distance, closer observation and examination of their structure reveal the spherical nature of these celestial objects.
