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 19,479,600 km across, Naos is 14 times the diameter of the Sun.
Its mass is 22 times the mass of the Sun.
The light reaching us from Naos tonight left it around 1,080 years ago.
Its surface sits at 40,000 K, hotter than the Sun at 5,772 K, which is what sets its colour.
It has been on record since the year 150.
