Question

A star is held together by:

gravity
nuclear fission
nuclear fusion
acceleration

Answer 1

The gravitational stress of the star keeps it all together

Answer 2

gravity

Step-by-step explanation:

A star is held together by its enormous gravity force that holds its material making it a huge ball of fire. stars have a density and high mass core. This core exerts a large amount of gravitational pull on the outer surfaces of the star and thus, binding the material into huge ball of fire, around which all planets revolve.
