21The Lyr is a rare star. It lies about 832 light-years from Earth, sits in the constellation Lyr, shines at apparent magnitude 4.35 and has spectral type K0II.
Its spectrum reads K0II — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.
Look for 21The Lyr in the constellation Lyr. At apparent magnitude 4.35, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 21The Lyr 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.
21The Lyr scores 36 points on Spacedle's rarity scale, which places it in the rare tier. Another 14 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Naked-eye visible, Orange K-type star, Bright giant and Intrinsically luminous (Mv < −2) — 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.
