The REsearch Consortium On Nearby Stars (RECONS) is an international group of astronomers founded in 1994 to investigate the stars nearest to the Solar System - with a focus on those within 10 parsecs, but as of 2012 the horizon was stretched to 25 parsecs. In part the project hopes a more accurate survey of local star systems will give a better picture of the star systems in the Galaxy as a whole.
SCR 1845−6357 is a binary system, 13.1 light-years away in the constellation Pavo. The primary is a faint red dwarf. It has a brown dwarf companion. The primary red dwarf was discovered in 2004 by Hambly et al., while the secondary brown dwarf was later discovered in 2006.
DENIS J1048−3956 is an exceptionally small, dim ultra-cool red dwarf star 13.2 light-years from Earth in the southern constellation of Antlia, among the stars closest to Earth. This star is very dim with an apparent magnitude of about 17, and requires a telescope with a camera to be seen. It was discovered in 2000 by Xavier Delfosse and Thierry Forveille, with the assistance of nine other astronomers.
Gliese 440, also known as LP 145-141 or LAWD 37, is an isolated white dwarf located 15.1 light-years from the Solar System in the constellation Musca. It is the fourth closest known white dwarf to the Sun, after Sirius B, Procyon B, and van Maanen's star.
LHS 288 is a red dwarf around 15.8 light years from the Sun, the closest in the constellation Carina. It is far too faint to be seen with the unaided eye, with an apparent magnitude of 13.92.
DENIS-P J020529.0−115925 is a brown dwarf system in the constellation of Cetus. It is located 64 light-years away, based on the system's parallax. It was first found in the Deep Near Infrared Survey of the Southern Sky.
LP 658-2 is a degenerate star in the constellation of Orion, the single known object in its system. It has an apparent visual magnitude of approximately 14.488.
2MASS J11145133−2618235, or 2M1114−26, or 2M1114−2618, or 2MASS 1114−26, or 2MASS J1114−2618) is a nearby brown dwarf of spectral class T7.5, located in constellation Hydra at approximately 18 light-years from Earth.
DENIS-P J1058.7-1548 is a brown dwarf of spectral type L3, located in constellation Crater at approximately 17.3 parsecs or 56.5 light-years from Earth. Its spectrum was used as a standard to define the spectral class L3 back in 1997. With a surface temperature of between 1700 and 2000 K, it is cool enough for clouds to form. Variations in its brightness in visible and infrared spectra suggest it has some form of atmospheric cloud cover.
LP 816-60 is a single red dwarf star of spectral type M4, located in constellation Capricornus at 18.6 light-years from Earth.
2MASS J18450079–1409036 and 2MASS J18450097–1409053 is a system of two red dwarf stars both of which have spectral types of M5, with projected separation of 3.2 seconds of arc. The system is located in the constellation Scutum. The Gaia parallaxes place the system at 18.2 parsecs from Earth. Kinematically, it belongs to young Argus association.
LHS 2090 is a red dwarf star of spectral type M6.5V, located in constellation Cancer at 20.8 light-years from Earth.
GJ 1128 is a red dwarf star of spectral type M4.0V, located in constellation Carina 21 light-years away from Earth. It is one of the closer stars to the Sun.
