KELT-20 b is an epic exoplanet. It lies about 445 light-years from Earth, shines at apparent magnitude 7.59, has spectral type A2 V and has an equilibrium temperature near 2,262 K.
So hot that iron vaporises on the dayside, blows around to the night side and rains back down as molten metal.
At apparent magnitude 7.59, it is an easy target for binoculars.
Like any astronomical target, KELT-20 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-20 b scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 15 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Ultra-hot Jupiter, Tidally locked, Blasted by starlight and Orbits a hot blue-white 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.
