Nu Draconis (also known as 𝜈 Dra, 𝜈 Draconis, where 𝜈 is the Greek letter nu, or traditionally as Kuma /ˈkjuːmə/) is a double star in the constellation Draco. The respective components are designated 𝜈¹ Draconis and 𝜈² Draconis. The second component is a spectroscopic binary star system.^[14]

This star, along with β Dra (Rastaban), γ Dra (Eltanin), μ Dra (Alrakis) and ξ Dra (Grumium) were Al ʽAwāïd, "the Mother Camels", which was later known as the Quinque Dromedarii.^[15]

In Chinese, 天棓 (Tiān Bàng), meaning Celestial Flail, refers to an asterism consisting of 𝜈 Draconis, ξ Draconis, β Draconis, γ Draconis and ι Herculis.^[16] Consequently, the Chinese name for 𝜈 Draconis itself is 天棓二 (Tiān Bàng èr, English: the Second Star of Celestial Flail.)^[17]

The two stars of the visual binary are considered to be a common proper motion pair on the basis of their very similar parallaxes, radial velocities, and proper motions, although no orbital motion can be observed.^[18]

𝜈¹ Draconis is an Am star, a slowly rotating chemically peculiar star with abnormally strong metallic absorption lines in its spectrum. Its spectral type of kA3hF0mF0 means that it would have a spectral class of A3 if determined solely from its calcium K lines, F0 if determined from its hydrogen lines, and F0 if determined from other metallic spectral lines.^[4]

𝜈² Draconis is a spectroscopic binary with a period of 38 days. The two stars are separated by 0.267 au on average, and they have an almost circular orbit with an eccentricity of 0.03.^[19][6] The primary is also an Am star, while the secondary has a low mass and luminosity and is only inferred from the orbital movement of the more massive star.^[7]
