LHS 1678 c is an anomaly exoplanet. It lies about 64.8 light-years from Earth, shines at apparent magnitude 12.6, has spectral type M2.0 V and has an equilibrium temperature near 511 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 12.6, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, LHS 1678 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.
LHS 1678 c scores 79 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 41 points would lift it into a rarer tier.
That score comes from 8 science badges — Confirmed exoplanet, Earth-sized, Tidally locked, Denser than iron, Multi-planet system, Found by TESS, 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.
