NN Ser d is an epic exoplanet. It lies about 1,682.4 light-years from Earth, shines at apparent magnitude 16.94, has spectral type WD and spans roughly 13.3 Earth radii.
Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.
At apparent magnitude 16.94, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, NN Ser d 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.
NN Ser d scores 59 points on Spacedle's rarity scale, which places it in the epic tier. Another 19 points would lift it into a rarer tier.
That score comes from 7 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Gas giant, Multi-planet system, Circumbinary (orbits both stars), Orbits a hot blue-white 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.
