	Gliese 623 Location of Gliese 623 in the constellation Hercules;

Gliese 623 is a dim double star 25.6 light years from Earth in the constellation Hercules. It was photographed by the NASA/ESA Hubble Space Telescope's Faint Object Camera in 1994. The binary system consists of two red dwarfs orbiting each other at a distance of 1.9 astronomical units.
