30Rho Vir is an uncommon variable star. It lies about 118.3 light-years from Earth, sits in the constellation Vir, shines at apparent magnitude 4.88 and has spectral type A0V.
Its spectrum reads A0V — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
Look for 30Rho Vir in the constellation Vir. At apparent magnitude 4.88, it can be glimpsed with the unaided eye under dark skies.
Like any astronomical target, 30Rho Vir 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.
30Rho Vir scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Naked-eye visible, On the zodiac, White A-type star, Main-sequence star, Barely variable (under 0.05 mag) 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.
