HD 164604 b

Extrasolar planet in the constellation Sagittarius

HD 164604 b is an extrasolar planet discovered in January 2010 in association with the Magellan Planet Search Program.[2] It has a minimum mass 2.7 times the mass of Jupiter and an orbital period of 606.4 days. Its star is classified as a K2 V dwarf and is roughly 124 light-years away from Earth.[3]

HD 164604 b is named Caleuche. The name was selected in the NameExoWorlds campaign by Chile, during the 100th anniversary of the IAU. Caleuche is a large ghost ship from southern Chilean mythology which sails the seas around the island of Chiloé at night.[4][5]

An astrometric measurement of the planet's inclination and true mass was published in 2022 as part of Gaia DR3.[1]
