HIP 77900 b is an epic exoplanet. It lies about 492 light-years from Earth, shines at apparent magnitude 6.15, has an equilibrium temperature near 2,507 K and spans roughly 12.1 Earth radii.
So hot that iron vaporises on the dayside, blows around to the night side and rains back down as molten metal.
At apparent magnitude 6.15, it is an easy target for binoculars.
Like any astronomical target, HIP 77900 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.
HIP 77900 b scores 77 points on Spacedle's rarity scale, which places it in the epic tier. Another 1 point would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Ultra-hot Jupiter, Directly imaged, Orbits a hot blue-white star and Orbits beyond Neptune's distance — 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.
