HD 219828 b is an epic exoplanet. It lies about 238.5 light-years from Earth, shines at apparent magnitude 8.04, has spectral type G0 IV and has an equilibrium temperature near 1,603 K.
Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.
At apparent magnitude 8.04, it is an easy target for binoculars.
Like any astronomical target, HD 219828 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 219828 b scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 27 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Neptune-like, Lava world, Tidally locked, Multi-planet system, Blasted by starlight 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.
