rho CrB c is a rare exoplanet. It lies about 57 light-years from Earth, shines at apparent magnitude 5.41, has spectral type G0 and has an equilibrium temperature near 448 K.
Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.
At apparent magnitude 5.41, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, rho CrB c 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.
rho CrB c 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, Neptune-like, Multi-planet system, Its star is visible to the naked eye and Orbits a Sun-like 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.
