HD 15170 is a trash star. It lies about 780.3 light-years from Earth, sits in the constellation Cet, shines at apparent magnitude 10.36 and has spectral type F3/F5IV/V.
Its spectrum reads F3/F5IV/V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HD 15170 in the constellation Cet. At apparent magnitude 10.36, a small backyard telescope will bring it into view.
Like any astronomical target, HD 15170 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 15170 scores 11 points on Spacedle's rarity scale, which places it in the trash tier. Another 4 points would lift it into a rarer tier.
That score comes from 3 science badges — Star, Yellow-white F-type star and Subgiant (leaving the main sequence) — 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.
