HD 147873 c is a rare exoplanet. It lies about 355.7 light-years from Earth, shines at apparent magnitude 7.96, has spectral type G1 V and has an equilibrium temperature near 374 K.
Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.
At apparent magnitude 7.96, it is an easy target for binoculars.
Like any astronomical target, HD 147873 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.
HD 147873 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, Gas giant, Multi-planet system, Orbits a Sun-like star 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.
