About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.13h 5m 40.18s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-25° 41' 6.0"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Centaurus
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.61 light-years (18.7 parsecs)

This pair of NASA Hubble Space Telescope images of the binary brown dwarf Kelu-1 trace the orbital motion of the two stars over a seven-year span as photographed by the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) on Hubble. In 1998, the "stars" were too close...
Graphic of Number of Stars vs. Spectral Type within 32 light-years of Earth
This diagram shows the various stellar populations within 32 light-years of Earth as measured by the RECONS survey. The largest population consists of red dwarfs, but the population of slightly lower mass brown dwarfs drops off precipitously. This is known as the "brown dwarf...
