TOI-178 b is a rare exoplanet. It lies about 204.5 light-years from Earth, shines at apparent magnitude 11.96, has spectral type K and has an equilibrium temperature near 1,040 K.
Genuinely comparable to Earth in size. Worlds in this narrow band are the ones every next-generation telescope is being pointed at.
At apparent magnitude 11.96, a small backyard telescope will bring it into view.
Like any astronomical target, TOI-178 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.
TOI-178 b scores 49 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Earth-sized, Tidally locked, Richly packed system and Found by TESS — 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.
