Lambda Velorum
Lambda Velorum designated, λ Velorum, officially named Suhail,[1] is a star in the southern constellation of Vela. With a mean apparent visual magnitude of 2.21,[2] this is the third-brightest star in the constellation of Vela and one of the brighter stars in the sky. The distance to this star can be measured directly using the parallax technique, yielding an estimated 545 light years from the Sun.[3]
The outer envelope of Suhail has an effective temperature of about 4,000 K, giving it the cool orange hue of a K-type star.[4] It is an Lc-type, slow irregular variable star with its brightness varying between apparent magnitudes +2.14 to +2.30.[5]
