What is the Schwarzschild radius?

The Schwarzschild radius is the radius of the event horizon of a non-rotating black hole. Nothing can escape from within this radius.

What is the Schwarzschild radius of the Sun?

About 2.95 km. The Sun would need to be compressed to this size to become a black hole.
