Of the main-sequence star types, stars more massive than 1.5 times that of the Sun (spectral types O, B, and A) age too quickly for advanced life to develop (using Earth as a guideline). On the other extreme, dwarfs of less than half the mass of the Sun (spectral type M) are likely to tidally lock planets within their habitable zone, along with ...
Both names are shown for each star in the tables and charts below. Each star's approximate position on the celestial sphere is given using the equatorial coordinate system. The celestial sphere is an imaginary globe of infinite size with the Earth at its center. [6]
The position marks are entered inward from the distance marks according to their declinations, connected by lines (doted when positive) representing the arcs of the declinations viewed edge-on. This list covers all known stars , white dwarfs , brown dwarfs , and sub-brown dwarfs within 20 light-years (6.13 parsecs ) of the Sun .

Stars less massive than 0.25 M ☉, called red dwarfs, are able to fuse nearly all of their mass while stars of about 1 M ☉ can only fuse about 10% of their mass. The combination of their slow fuel-consumption and relatively large usable fuel supply allows low mass stars to last about one trillion ( 10 × 10 12 ) years; the most extreme of 0. ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
The following are lists of stars. Stars are astronomical objects that spend some portion of their existence generating energy through thermonuclear fusion . By location
Below there are lists the nearest stars separated by spectral type. The scope of the list is still restricted to the main sequence spectral types: M, K, F, G, A, B and O. It may be later expanded to other types, such as S, D or C. The Alpha Centauri star system is the closest star system to the Sun.
