The Schwarzschild metric is a solution to the Einstein field equations of general relativity that describes the gravitational field outside a spherical, non-rotating, and uncharged mass such as a planet or a non-rotating star. It is one of the simplest and most important solutions in general relativity, providing insights into the geometry of spacetime in the presence of a gravitational source.
