What is the minimum size for a star?
gpt
In terms of mass, about 0.075 the mass of our Sun. That is the lowest mass a star can be while still maintaining fusion reactions. If you mean in terms of size then that would be neutron stars which weigh more than our Sun but have a radius of only about 10-20 km.
