- Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ross 154 (V1216 Sgr) is a red dwarf star approximately 3.0 pc or 9.68 light years from the Sun. It is the nearest star in the southern constellation Sagittarius, and one of the closest to the Sun. Its nearest neighbor is Barnard's star, located 1.66 pc (5.41 ly) away. This star was first catalogued by Frank Elmore Ross in 1925, and formed part of his fourth list of new variable stars. It was found to be a UV Ceti-type flare star, with a mean time between major flares of about two days. Typically, the star will increase by 3–4 magnitudes during a flare. However, at 11th magnitude, this star is much too faint to be viewed with the unaided eye and requires at least a 65 mm telescope aperture to be seen under ideal conditions.
