HD 21021 is a trash star. It lies about 95.1 light-years from Earth, sits in the constellation For, shines at apparent magnitude 9.28 and has spectral type K4V.
Its spectrum reads K4V — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.
Look for HD 21021 in the constellation For. At apparent magnitude 9.28, a small backyard telescope will bring it into view.
Like any astronomical target, HD 21021 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.
HD 21021 scores 8 points on Spacedle's rarity scale, which places it in the trash tier. Another 7 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Orange K-type star and Main-sequence 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.
