Theta Columbae is a blue subgiant star in the constellation Columba.

This star, along with ζ CMa, λ CMa, γ Col, δ Col, κ Col, λ Col, μ Col and ξ Col, were Al Ḳurūd (ألقرد - al-qird), the Apes.[1][2]

4.8 million years ago, Theta Columbae was only 7 light years away from the Solar System, and was brighter than Venus.[3]

In Chinese, (Sūn), meaning Grandson, refers to an asterism consisting of θ Columbae and κ Columbae.[4] Consequently, θ Columbae itself is known as 孫二 (Sūn èr, English: the Second Star of Grandson.).[5]
