LHS 1815 b is a rare exoplanet. It lies about 97.3 light-years from Earth, shines at apparent magnitude 12.17, has spectral type M1 and has an equilibrium temperature near 617 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 12.17, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, LHS 1815 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.
LHS 1815 b 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 4 science badges — Confirmed exoplanet, Earth-sized, Tidally locked 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.
