Kepler-1660 AB b is an uncommon exoplanet. It lies about 3,876.5 light-years from Earth, shines at apparent magnitude 13.6, has spectral type F7 V and has an equilibrium temperature near 415 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 13.6, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, Kepler-1660 AB 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.
Kepler-1660 AB b scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Gas giant, Circumbinary (orbits both stars) and Found by Kepler — 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.
