IRAS 04125+2902 b is a rare exoplanet. It lies about 519.4 light-years from Earth, shines at apparent magnitude 15.64, has an equilibrium temperature near 854 K and spans roughly 10.74 Earth radii.
It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.
At apparent magnitude 15.64, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, IRAS 04125+2902 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.
IRAS 04125+2902 b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Tidally locked, Found by TESS and Two suns in its sky — 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.
