Trivia
Hard to believe
- True brightness. It pours out about 1.1 million times as much light as the Sun. It only looks ordinary because it is so far away.
What it actually is
- Spectral class. Its spectrum reads G9III: — a G-type star: the very same spectral class as our own Sun.
- Where it is in life. It is a giant. It has already exhausted its core hydrogen and swollen up enormously in response.
Find it in the sky
- How to spot it. At magnitude 9.8 you'll want a small backyard telescope, over in Norma.
- Southern sky. It rides the southern half of the sky — an easier target the further south you are.
- Best time of year. It stands highest in the middle of the night around May — that's when to go looking.
Its true colour
- Its true colour. Measured through blue and visual filters it comes out deep orange-red (B−V 1.8) — one of the coolest surfaces a star can have while still fusing.
By the numbers
- Surface temperature. Its colour puts the surface at roughly 3420 K, against the Sun's 5778 K.

How to see it
Look for HIP 80596 in the constellation Nor. At apparent magnitude 9.75, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 80596 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
Why HIP 80596 is an uncommon star
HIP 80596 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Sun-like G-type star, Giant star and Deep red star — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
