Gliese 22
Gliese 22, also catalogued V547 Cassiopeiae, is a hierarchical star system approximately 33 light-years away in the constellation of Cassiopeia.

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.
