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.

Its mass is 3.1 times the mass of the Sun.
The light reaching us from Rhombus tonight left it around 163 years ago.
Its surface sits at 5,196 K, cooler than the Sun at 5,772 K, which is what sets its colour.
It has been on record since 1756.
