NotesThere are several stars in Orion given the traditional name Tabit ('constant one'), but the name is most commonly used for this star, Pi3 Orionis. Pi2 Orionis, a little to the north, is also sometimes called Tabit, as is Upsilon Orionis, some distance to the south and east near the bright star Rigel.

A line pointing through the three stars of the Orion's Belt, out towards Taurus, guides the way to this pale yellow star. Unlike most of Orion's prominent stars, binary Tabit is fairly close to the Sun: just 26 light years away.
