Look for HR 6870 in the constellation Sgr. At apparent magnitude 5.33, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 6870 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.
HR 6870 scores 58 points on Spacedle's rarity scale, which places it in the epic tier. Another 20 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Naked-eye visible, Toward the galactic centre, On the zodiac, Hot blue B-type star, Supergiant, Blue-white star and Barely variable (under 0.05 mag) — 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.
