Gamma2 Normae
Gamma2 Normae, Latinized from γ2 Nor, is the brightest star in the southern constellation of Norma. Its apparent magnitude is 4.02 – making it a faint star but visible to the naked eye. Based upon an annual parallax shift of 23.57 mas as seen from Earth, this star is located roughly 138 light years away. It is moving closer to the Sun with a radial velocity of.
This is an evolved, orange-hued giant of spectral type K0 III. A red clump star, it has started the fusion of helium at its core and is now in the evolutionary stage known as the horizontal branch. The star is around 2.16 times as massive as the Sun and has grown to a diameter 10.35 times that of the Sun. The star is radiating 50 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,763 K.
Gamma2 Normae is a double star, with a magnitude 10 companion away. The pair has been previously identified as a binary star system, but parallax measurements the Gaia spacecraft data showed the companion star to be much more distant. A white dwarf located 24.38" away has similar distance and proper motion with Gamma2 Normae.
