Mu Velorum (μ Vel, μ Velorum) is a binary star in the constellation Vela. It is approximately 116 light years from Earth. Mu Velorum is approximately 38 solar diameters, almost as big as Aldebaran.
The primary component, Mu Velorum A, is a yellow G-type giant with an apparent magnitude of +2.69. The companion is a yellow G-type main sequence dwarf with an apparent magnitude of +6.6. The two stars are 0.7 arcseconds apart and complete one orbit every 116.24 years.
This star has 0.75 times the mass of the Sun.[1]
