List of nearest stars

Artist's conception of a red dwarf star, the most common type of star in the Sun's stellar neighborhood, and in the universe. Although termed a red dwarf, the surface temperature of this star would give it an orange hue when viewed from close proximity

This list of nearest stars contains all known stars and brown dwarfs at a distance of up to five parsecs (16.308 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 9 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.[1] 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.

[edit] List

Stars visible to the unaided eye have their magnitude shown in light blue below. The classes of the stars and brown dwarfs are shown in the color of their spectral types (these colors are derived from conventional names for the spectral types and do not represent the star's observed color). Some of the parallax and distance results are preliminary measurements.[2]

[edit] Map of nearby stars

The following map shows all of the star systems within 14 light-years of the Sun (shown as Sol), except for two brown dwarfs discovered after 2009. Double and triple stars are shown "stacked", but the true location is the star closest to the central plane. Color corresponds to the table above.

[edit] Future and past

Distances of the nearest stars from 20,000 years ago until 80,000 years in the future

Ross 248, currently at a distance of 10.3 light-years, has a radial velocity of −81 km/s. In about 31,000 years it may be the closest star to the Sun for several millennia, with a minimum distance of 0.927 parsecs (3.02 light-years) in 36,000 years.[24] Gliese 445, currently at a distance of 17.6 light-years, has a radial velocity of −119 km/s. In about 40,000 years it will be the closest star for a period of several thousand years.[24]
