As many as 512 or more stars of spectral type "G" (not including white dwarf stellar remnants) are currently believed to be located within 100 light-years or (or 30.7 parsecs) of Sol -- including Sol itself. Only around 64 are located within 50 light-years (ly), while some 448 are estimated to lie between 50 and 100 light-years - a volume of space that is seven times as large as the inner sphere within 50 ly of Sol. Humanity has presently managed to push out approximately 85 ly from Sol in all direction, meaning an enormous number colonies of all sizes exist. | As many as 512 or more stars of spectral type "G" (not including white dwarf stellar remnants) are currently believed to be located within 100 light-years or (or 30.7 parsecs) of Sol -- including Sol itself.
