LTT 3780 c is a rare exoplanet. It lies about 71.7 light-years from Earth, shines at apparent magnitude 13.14, has spectral type M3.5 V and has an equilibrium temperature near 359 K.
It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.
At apparent magnitude 13.14, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, LTT 3780 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.
LTT 3780 c scores 40 points on Spacedle's rarity scale, which places it in the rare tier. Another 10 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Sub-Neptune, 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.
