Binary star system in the constellation Gemini
Phi Geminorum , Latinized from φ Geminorum , is a binary star [ 6] constellation Gemini , to the southeast of Pollux . It is visible to the naked eye with an apparent visual magnitude of 4.95.[ 2] parallax shift of 14.66 mas ,[ 1] light years from the Sun .
The two components of this system have a circular orbit with a period of 582 days.[ 6] A-type main sequence star with a stellar classification of A3 V.[ 3] projected rotational velocity of 165[ 9] oblate shape with an equatorial bulge that is 6% larger than the polar radius.[ 3] mass of the Sun and radiates 36.5[ 8] solar luminosity from its outer atmosphere at an effective temperature of 8,551[ 7]
