WASP-18 b is an anomaly exoplanet. It lies about 402.7 light-years from Earth, has an equilibrium temperature near 2,429 K, spans roughly 13.9 Earth radii and weighs about 3,241.85 Earth masses.
So hot that iron vaporises and rains back down as molten metal.
Like any astronomical target, WASP-18 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.
WASP-18 b scores 73 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 22 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Ultra-short period, Multi-planet system and Blasted by starlight — 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.
