HD 198140 is a rare star. It lies about 1,022.4 light-years from Earth, sits in the constellation Cap, shines at apparent magnitude 10.64 and has spectral type C.
Its spectrum reads C — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
Look for HD 198140 in the constellation Cap. At apparent magnitude 10.64, a small backyard telescope will bring it into view.
Like any astronomical target, HD 198140 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 198140 scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.
That score comes from 5 science badges — Star, Distant (over 1,000 light-years), On the zodiac, Carbon star (sooty red) and Deep red 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.
