High Quality Content by WIKIPEDIA articles! This list contains all known stars and brown dwarfs at a distance of up to 5 parsecs (16.3 light-years) from the Solar System, ordered by increasing distance. In addition to the Solar System, there are another 51 stellar systems currently known lying within this distance. These systems contain a total of 61 hydrogen-fusing stars and nine brown dwarfs. Despite the relative proximity of these objects to the Earth, only nine of them have an apparent magnitude less than 6.5, which means only about 13% of these objects can be observed with the naked eye. Besides the Sun, only three are first-magnitude stars: Alpha Centauri, Sirius, and Procyon. All of these objects are located in the Local Bubble, a region within the Orion–Cygnus Arm of the Milky Way Galaxy.
