KELT-21 b is an epic exoplanet. It lies about 1,535.8 light-years from Earth, has an equilibrium temperature near 2,051 K, spans roughly 17.78 Earth radii and weighs about 1,242.72 Earth masses.
Its surface is likely an ocean of molten rock.
Like any astronomical target, KELT-21 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.
KELT-21 b scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Blasted by starlight and Distant (>1000 ly) — 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.
