47 UMa d is an epic exoplanet. It lies about 45 light-years from Earth, shines at apparent magnitude 5.03, has spectral type G0V and has an equilibrium temperature near 92 K.
A deep-frozen world, too far from its star's warmth for anything to stay liquid.
At apparent magnitude 5.03, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 47 UMa d 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.
47 UMa d scores 53 points on Spacedle's rarity scale, which places it in the epic tier. Another 25 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, 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.
