HIP 89743 is a rare star. It lies about 1,370.4 light-years from Earth, sits in the constellation Ser, shines at apparent magnitude 9.34 and has spectral type O9.5V.
Its spectrum reads O9.5V — an O-type star — the hottest, rarest main class there is. Fewer than one star in a million is an O, and none of them lasts long.
Look for HIP 89743 in the constellation Ser. At apparent magnitude 9.34, a small backyard telescope will bring it into view.
Like any astronomical target, HIP 89743 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.
HIP 89743 scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.
That score comes from 4 science badges — Star, Distant (over 1,000 light-years), Blazing O-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.
