An orange dwarf (i.e., main sequence) star located in the northwest part of the constellation Draco. It is a relatively close neighbor of the Sun, at a distance of under 19 light years.
Sigma Draconis is included in a list of the top 100 target stars for NASA's planned Terrestrial Planet Finder. Although no planets have been found so far orbiting Sigma Draconis, searches will be made over the next decade or so to check for the existence of Earth-like worlds in the star's habitable zone.
