While astronomers know of no stars lying within one parsec of Sol, they find more stars within 10 parsecs every year — which is the mission of the Research Consortium on Nearby Stars (RECONS). Including Sol itself, over 414 celestial objects (including white and brown dwarfs) are currently believed to be located within 10 parsecs (pc) — (32.6 light-years (ly) — of Sol. While there are no bright blue stars of spectral “O” or “B” in the Solar neighborhood, most of the 74 nearby AFGK bright stars have probably been found, although a few dim, late orange-red K-type dwarfs may yet be identified. On the other hand, although over 273 very dim but nearby red dwarf stars (of spectral type “M”) have a measured distance of roughly 10 pc from Sol, many more probably remain to be found. Similarly, at least 48 substellar and extremely faint, nearby brown dwarfs, have been found as of April 25, 2014. Some astronomers believe, however, that the current count of at least 21 nearby white dwarf stellar remnants will not be significantly raised despite continuing observations.

Nearby Celestial Objects by Type, Number, and Mass

Minimum Solar-masses assumed for objects without mass estimates:
red stars (M=0.08); white dwarfs (D=0.5); and brown dwarfs (0.05).
