NGTS-30 b is a common exoplanet. It lies about 777.5 light-years from Earth, shines at apparent magnitude 12.54, has an equilibrium temperature near 500 K and spans roughly 10.4 Earth radii.
Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.
At apparent magnitude 12.54, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, NGTS-30 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.
NGTS-30 b scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Found by TESS and Orbits a Sun-like star — 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.
