GZ Velorum is a single,[12] orange-hued star in the southern constellation of Vela. It is a faint star but visible to the naked eye, having an apparent visual magnitude of 4.58.[3] The star is located around 1,300 light years from Earth, as determined from its annual parallax shift of 2.4 mas.[2] It is moving further away with a heliocentric radial velocity of +13 km/s.[6]
This is a bright giant star with a stellar classification of K2.5 II.[4] It is a slow irregular variable of type LC[5] with a frequency of 0.16585 cycles per day.[13] In the R (red) band, the magnitude of the star ranges from 3.43 down to 3.81.[5] The measured angular diameter of this star, after correction for limb darkening, is 3.17±0.04 mas.[14] At the estimated distance of GZ Vel, this yields a physical size of about 140 times the radius of the Sun.[15]
GZ Vel is 30 million years old with 9 times the mass of the Sun.[8] It is radiating 9,241[3] times the Sun's luminosity from its photosphere at an effective temperature of 4,140 K.[3]
