}}{{starbox end}}Xi Columbae is a binary star[10] system in the southern constellation of Columba. With an apparent visual magnitude of 4.97,[3] it is faintly visible to the naked eye. To ancient Arabian astronomers, this star, along with ζ CMa, λ CMa, γ Col, δ Col, θ Col, κ Col, λ Col and μ Col, formed Al Ḳurūd (ألقرد - al-qird), the Apes.[20] Based upon an annual parallax shift of 9.80 mas,[ it is located around 330 light years from the Sun.]
This is an astrometric binary[22] with an orbital period of 1,420.6 days and an eccentricity of 0.39.[10] The primary is an evolved K-type giant star with a stellar classification of {{Nowrap|K1 III CNII}}.[4] It is a member of the HR 1614 supergroup[25] and shows an overabundance of CN.[4] The companion has a mass of at least 59% that of the Sun.[10]
