61 Cygni is an orange binary system with a separation distance of 12.7 billion kilometres. The two stars revolve around each other in approximately 720 years and both are about 20 billion years old.

Two dark companions of unconfirmed masses 0.01 and 0.008 relative to our Sun seem to orbit 61 Cygni A (spectral type K5) and 61 Cygni B (spectral type K7) respectively.



PROCYON 11.43 LIGHT YEARS 

MASS
A : 1.77
B : 0.63

LUMINOSITY
7.6 : A
0.00050 : B


A binary system consisting of a bright yellow-white subgiant (spectral type F5) and a faint white dwarf companion (slightly yellowish in colour, spectral type DF) that is nearing the end of its stellar evolution. The two stars orbit each other in 40 years and are separated by 2.4 billion kilometres of presumably empty space.



EPSILON INDI 11.81 LIGHT YEARS 

MASS
