Proxima Cen d is an epic exoplanet. It lies about 4.2 light-years from Earth, shines at apparent magnitude 11.01, has spectral type M5.5 V and has an equilibrium temperature near 282 K.
One of the closest objects of its kind to the Sun — a first port of call for any interstellar mission we ever build.
At apparent magnitude 11.01, a small backyard telescope will bring it into view.
Like any astronomical target, Proxima Cen 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.
Proxima Cen d scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 12 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Stellar next door (<10 ly), Tidally locked, Multi-planet system, Orbits a red dwarf 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.
