Adopted distance estimates[edit]

Object Parallax, mas Distance, pc Distance, ly Source
Systems with a G-type main-sequence star (yellow dwarf) as primary member.
Sun 0 0 The distances are measured from the Sun (or from Earth — difference of positions of Sun and Earth is too small compared with interstellar distances), and distance from Sun to Sun is 0.
Alpha Centauri AB 747.1 ± 1.2 1.3385+0.0022
−0.0021
4.366 ± 0.007 Söderhjelm (1999)[1]
Alpha Centauri C 768.7 ± 0.3 1.3009 ± 0.0005 4.243 ± 0.0017 Benedict et al. (1999)[2]
