Trivia
Hard to believe
- True brightness. It pours out about 597 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 sdF: — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
- Where it is in life. It is a subdwarf: an old, metal-poor star from the galaxy's early days, a little smaller and fainter than a main-sequence star of the same colour.
Find it in the sky
- How to spot it. At magnitude 10.4 you'll want a small backyard telescope, over in Canis Minor.
- Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
- Best time of year. It stands highest in the middle of the night around January — that's when to go looking.
Its true colour
- Its true colour. Measured through blue and visual filters it comes out yellow-white (B−V 0.5) — a shade brighter and crisper than our own Sun.
- Why no green stars. No star ever looks green: a surface hot enough to peak in green also floods out plenty of red and blue, and your eye blends the mixture back to white.

How to see it
Look for HIP 37671 in the constellation CMi. At apparent magnitude 10.39, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 37671 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 37671 is a trash star
HIP 37671 scores 6 points on Spacedle's rarity scale, which places it in the trash tier. Another 9 points would lift it into a rarer tier.
That score comes from 2 science badges — Star and Yellow-white F-type 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.
