Gamma2 Normae

This is an evolved, yellow-hued giant of spectral type K0 III around 2.16 times as massive as the Sun that has swollen to a diameter 10 times that of the Sun. It is a red clump star on the horizontal branch, which indicates it is generating energy through helium fusion at its core. The star is radiating 51 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,699 K.

Gamma² Normae is a close double, with a magnitude 10 companion. The pair has been previously identified as a binary star system, but the second release of Gaia data showed the companion star to be much more distant. Another 16-magnitude star, with a temperature of 5,972 K, is listed 20" away with nearly the same parallax and proper motion as Gamma² Normae.

γ¹ Nor is a yellow supergiant located nearby on the celestial sphere, but is much further away from Earth and nearly a magnitude fainter.
