18 Del b is an uncommon exoplanet. It lies about 248.6 light-years from Earth, shines at apparent magnitude 5.51, has spectral type G6 III and has an equilibrium temperature near 453 K.
Denser than Earth — a solid world of rock and iron, with no meaningful atmosphere to speak of by mass.
At apparent magnitude 5.51, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 18 Del 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.
18 Del b scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Its star is visible to the naked eye 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.
