Frequently Asked Questions
What is the Schwarzschild radius?
The Schwarzschild radius is the distance from a mass at which the escape speed equals the speed of light. Light emitted at or below this radius cannot escape, which is why the emission radius must be larger.
Is gravitational redshift the same as Doppler shift?
No. Gravitational redshift comes from light climbing out of a gravity well, while Doppler shift comes from relative motion. This calculator gives only the static gravitational part.
How large is the Sun gravitational redshift?
It is very small, only about two parts per million at the solar surface, because the Sun is far from being a compact object like a neutron star.
