Trivia
Hard to believe
- True brightness. It pours out about 1.9 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 F6V — an F-type star — a little hotter, whiter and shorter-lived than the 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 9.1 you'll want a small backyard telescope, over in Gemini.
- Northern sky. It rides the northern half of the sky — an easier target the further north you are.
- Best time of year. It stands highest in the middle of the night around December — that's when to go looking.
Its true colour
- Its true colour. Measured through blue and visual filters it comes out brilliant white (B−V 0.1) — hotter and whiter than the Sun, the colour of Sirius or Vega.
- 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 HD 43206 in the constellation Gem. At apparent magnitude 9.13, a small backyard telescope will bring it into view.
Like any astronomical target, HD 43206 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 43206 is a trash star
HD 43206 scores 11 points on Spacedle's rarity scale, which places it in the trash tier. Another 4 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, On the zodiac, Yellow-white F-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.
