KOINTREAU-4 b is a rare exoplanet. It lies about 474.3 light-years from Earth, shines at apparent magnitude 15.9, has spectral type M4.5 and spans roughly 12.2 Earth radii.
Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.
At apparent magnitude 15.9, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, KOINTREAU-4 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.
KOINTREAU-4 b scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 5 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Directly imaged, Orbits a red dwarf 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.
