HAT-P-51 b is an epic exoplanet. It lies about 1,435.4 light-years from Earth, shines at apparent magnitude 13.51, has spectral type G7 and has an equilibrium temperature near 1,168 K.
It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.
At apparent magnitude 13.51, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, HAT-P-51 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.
HAT-P-51 b scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 23 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Gas giant, Hot Jupiter, Tidally locked, Puffy low-density world 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.
