Assume that the mass density of the Sun is uniform and treat solar radiation as blackbody radiation It s given that the surface tem perature of the Sun is 6000 K and assume that the Sun continues giving energy at the same rate in future If the source of Sun s ra diated energy was its gravitational potential energy instead of the nuclear fusion then the Sun will cease to exist in a time of the order of x 10 years 2 10 million years 2 X3 1 billion years 3 X4 1000 years
