HD 142022 A b is a rare exoplanet. It lies about 111.8 light-years from Earth, shines at apparent magnitude 7.7, has spectral type G9 IV-V and has an equilibrium temperature near 156 K.
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 7.7, it is an easy target for binoculars.
Like any astronomical target, HD 142022 A 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.
HD 142022 A b scores 38 points on Spacedle's rarity scale, which places it in the rare tier. Another 12 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Eccentric orbit, 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.
