Stars spend most of their lives fusing hydrogen into helium in their core, and it's the balance between that outward pressure and gravity pulling inward that fixes how big and how bright a star gets.
At 14,414,200 km across, Gamma2 Normae is 10 times the diameter of the Sun.
Its mass is 2.1 times the mass of the Sun.
The light reaching us from Gamma2 Normae tonight left it around 138 years ago.
Its surface sits at 4,763 K, cooler than the Sun at 5,772 K, which is what sets its colour.
It has been on record since 1756.
