HIP 66074 b is a common exoplanet. It lies about 115.6 light-years from Earth, shines at apparent magnitude 10.25, has an equilibrium temperature near 193 K and spans roughly 12.9 Earth radii.
Its density says rock, though lighter than Earth's mix: probably less iron, or a thick shell of water and ice over the top.
At apparent magnitude 10.25, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 66074 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.
HIP 66074 b scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 4 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Eccentric orbit — 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.
