There is a way to find that out. We can use Schwarzschild radius to find the point at which an objects radius crosses the event horizon and thus becomes a black hole; Rs=2GM/c2, Rs being the Schwarzschild radius, G being the gravitational constant (6.67xe-11), M being the things mass, and c being the speed of light.
