HIP 10090 b is an uncommon exoplanet. It lies about 268.7 light-years from Earth, shines at apparent magnitude 8.94, has spectral type K0 and has an equilibrium temperature near 163 K.
Its density says rock, though lighter than Earth's mix: probably less iron, or a thick shell of water and ice over the top.
At apparent magnitude 8.94, it is an easy target for binoculars.
Like any astronomical target, HIP 10090 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.
HIP 10090 b scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Multi-planet system and Orbits a Sun-like 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.
