HD 117777 is an uncommon variable star. It lies about 1,456.1 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 9.24 and has spectral type F2V.
Its spectrum reads F2V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
Look for HD 117777 in the constellation CVn. At apparent magnitude 9.24, a small backyard telescope will bring it into view.
Like any astronomical target, HD 117777 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 117777 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), Yellow-white F-type star, Main-sequence star, Gently variable and A named variable 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.
