HD 133131 B b is an epic exoplanet. It lies about 167.3 light-years from Earth, shines at apparent magnitude 8.41, has spectral type G2 V and has an equilibrium temperature near 112 K.
A deep-frozen world, too far from its star's warmth for anything to stay liquid.
At apparent magnitude 8.41, it is an easy target for binoculars.
Like any astronomical target, HD 133131 B 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 133131 B b scores 62 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.
That score comes from 8 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, Eccentric orbit, Multi-planet system, Orbits a Sun-like star and Two suns in its sky — 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.
