Lista över de närmaste stjärnorna
Denna lista över de närmaste stjärnorna innehåller alla kända stjärnor och bruna dvärgar inom 5 parsec (16 ljusår) från jorden, ordnade efter avstånd. Förutom solsystemet finns det ytterligare 50 stjärnsystem inom det avståndet. Dessa system innehåller totalt 61 stjärnor med fusion och åtta bruna dvärgar. Alla finns inom Vintergatan. Bara nio av dessa himlakroppar är ljusstarka nog att se med blotta ögat.[1]. Bara tre av dem, förutom solen, finns med i Lista över de ljusaste stjärnorna: Alfa Centauri, Sirius, och Procyon.
Lista
Stjärnor synliga med blotta ögat har sin magnitud i ljusblått nedan. Vissa parallaxer och avstånd är preliminära data.[2]

Karta i 3-D över de närmaste stjärnorna
Följande karta visar alla stjärnsystem inom 14 ljusår från solen, förutom den nyupptäckta bruna dvärgen UGPS 0722-05. Dubbel- och trippelstjärnor visas "staplade"; i varje stapel visar stjärnan närmast mittplanet den korrekta positionen. Färger som i tabellen ovan.

Framtiden och det förflutna
Stjärnorna rör sig hela tiden i rymden, i sina banor runt Vintergatan. Vilken stjärna som är närmast solen kommer därför att variera med tiden, vilket visas i figuren här bredvid.

Nearby Stars (14ly Radius).svg
A spatial representation of every star within 14 light-years of Sol. There are 32 known stars in this region, including Sol. The stars are coloured according to the spectral type, which may not reflect the actual colour. Please see this Wikipedia article for the listing of stars. If a star is double or triple the stars are shown stacked vertically: the actual position is the star closest to the centre plane. The stars on this map may not all be visible to the naked eye, as many are dwarf stars. Some of this information may be preliminary and not entirely accurate as a result. The coordinate system is right ascension and declination. Hours of RA are marked, as well as distance in multiples of 5 light-years.
