Lambda Velorum (λ Vel or λ Velorum) is a star in the constellation Vela. It also has the traditional name Suhail (which, confusingly, is sometimes used for Gamma Velorum).

Lambda Velorum is a supergiant or bright giant star of spectral class K5. Supergiant stars use up their hydrogen "fuel" much faster than do smaller stars and λ Velorum is estimated to be only some 27 million years old. It is classified as an irregular variable star and its brightness varies from magnitude +2.14 to +2.30.

Etymology

The medieval name Suhail (Al Suhail, Alsuhail, Suhail Alwazn) is short for the Arabic "suhayl al-wazn" "The glorious (star) of the cycle".
