Ross 154 is an anomaly variable star. It lies about 9.7 light-years from Earth, sits in the constellation Sgr, shines at apparent magnitude 10.37 and has spectral type M3.5Ve.
One of the closest objects of its kind to the Sun — a first port of call for any interstellar mission we ever build.
Look for Ross 154 in the constellation Sgr. At apparent magnitude 10.37, a small backyard telescope will bring it into view.
Like any astronomical target, Ross 154 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.
Ross 154 scores 83 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 37 points would lift it into a rarer tier.
That score comes from 12 science badges — Variable star, Stellar next door (<10 ly), Has a proper name, Toward the galactic centre, On the zodiac, Cool red M-type star, Main-sequence star and Deep red 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.
