HD 22781 b is a common exoplanet. It lies about 106.3 light-years from Earth, shines at apparent magnitude 8.78, has spectral type K1 and has an equilibrium temperature near 193 K.
Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.
At apparent magnitude 8.78, it is an easy target for binoculars.
Like any astronomical target, HD 22781 b 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.
HD 22781 b scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 4 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Eccentric orbit — 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.
