HR 3170 is an epic variable star. It lies about 2,090.7 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 5.25 and has spectral type M2II.
Its spectrum reads M2II — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
Look for HR 3170 in the constellation Pup. At apparent magnitude 5.25, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, HR 3170 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 3170 scores 61 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.
That score comes from 9 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Cool red M-type star, Bright giant, Deep red star, Intrinsically luminous (Mv < −2) and Gently variable — 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.
