Gliese 22, also catalogued V547 Cassiopeiae or shortened to Gl 22, is a hierarchical star system approximately 33 light-years away in the constellation of Cassiopeia. The system consists of two red dwarf stars, Gliese 22A and Gliese 22B in an outer orbit of about 320 years, and a brown dwarf, Gliese 22C, which orbits Gliese 22A in about 16 years. As of 2008, it was announced that a possible extrasolar planet, Gliese 22B b, or brown dwarf orbits Gliese 22B but this is currently unconfirmed.

- Gliese 22 (V547 Cassiopeiae / Gl 22) est un système d'étoiles à 33 années-lumière de la Terre dans la constellation de Cassiopée. Le système est constitué de deux étoiles naines rouges et d'une étoile naine brune. En 2008, il a été annoncé qu'une éventuelle exoplanète (Gliese 22 B) orbitait dans le système, mais cette planète n'a pas encore été confirmée.
