In the center of our galaxy, hundreds of stars closely orbit a supermassive black hole. Most of these stars have large enough orbits that their motion is described by Newtonian gravity and Kepler’s laws of motion. But a few orbits so closely that their orbits can only be accurately described by Einstein’s theory of general relativity. The star with the smallest orbit is known as S62. Its closest approach to the black hole has it moving more than 8% of light speed.
Fastest Star Ever Seen is Moving at 8% the Speed of Light - Universe Today
A star orbiting the black hole in the center of our galaxy is moving so fast it can only be described relativistically.
