Trivia
Hard to believe
- True brightness. It pours out about 903.6 thousand 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 G3V — a G-type star: the very same spectral class as our own Sun.
- Where it is in life. It is on the main sequence, quietly fusing hydrogen in its core exactly as the Sun does.
Find it in the sky
- How to spot it. At magnitude 9.9 you'll want a small backyard telescope, over in Lupus.
- 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.
What's in a name
- Its catalogue. The HD number is from the Henry Draper Catalogue, in which Annie Jump Cannon personally classified the spectra of nearly 400,000 stars — still the largest such feat by one person.

How to see it
Look for HD 134156 in the constellation Lup. At apparent magnitude 9.94, a small backyard telescope will bring it into view.
Like any astronomical target, HD 134156 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 HD 134156 is a trash star
HD 134156 scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Sun-like G-type star and Main-sequence 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.
