Tucana Horologium association

(THA, Tuc-Hor)
(nearby stellar association)

The Tucana Horologium association (abbreviated THA) is a nearby stellar association. A THA star is a star in the association. AB Pictoris (a K-type star with a substantial orbiting object on the line between extra-solar planet and brown dwarf) was considered a member but a recent determination says not, though it is in within the association's volume.
