Answer 1

Heya mate is it really your asking this question seriously or having for a fun

Answer 2

Explanation:

If it is smaller than this, then it would not be a star anymore, but rather a cold and dark stellar remnant. In any possible hypothesis, if the Sun shrank smaller than the size of Earth, this Sun would not have the mass to create fusion reaction and would quickly burn out completely.
