tau Cet f is an epic exoplanet. It lies about 11.8 light-years from Earth, shines at apparent magnitude 3.5, has spectral type G8.5V and has an equilibrium temperature near 202 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 3.5, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, tau Cet f 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.
tau Cet f scores 61 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Nearby (<25 ly), Super-Earth, Multi-planet system, Its star is visible to the naked eye, Orbits a Sun-like star and Disputed — it may not be there at all — 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.
