HD 31253 b is a trash exoplanet. It lies about 189.6 light-years from Earth, shines at apparent magnitude 7.13, has spectral type F8 and has an equilibrium temperature near 348 K.
Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.
At apparent magnitude 7.13, it is an easy target for binoculars.
Like any astronomical target, HD 31253 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 31253 b scores 9 points on Spacedle's rarity scale, which places it in the trash tier. Another 6 points would lift it into a rarer tier.
That score comes from 2 science badges — Confirmed exoplanet and Gas giant — 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.
