Gliese 809 is a red dwarf star in the constellation Cepheus,[5] forming the primary component of a multi-star system. A visual magnitude of 8.55 makes it too faint to see with the naked eye. It is part of the Gliese Catalogue of Nearby Stars and is located about 23 light-years (ly) from the Solar System. Gliese 809 has about 70.5%[6] the radius of the Sun and 61.4%[2] of the Sun's mass. It has a metallicity of −0.06, which means that the abundance of elements other than hydrogen and helium is just 87.1% that of the Sun.[2]

This is a high

semi-minor axis of 25,542 ly.[5]
