Gravitational radius of massive body¶
The gravitational radius, or Schwarzschild radius, is a characteristic radius defined for any physical body with mass. This is the radius of the sphere on which the event horizon created by this mass would be located (from the point of view of general theory of relativity) if it were distributed spherically symmetrically, would be stationary (in particular, it would not rotate, but radial movements are permissible) and would lie entirely inside this sphere.
