KRW 2 Based on a comparison of images spanning 23 years, Krawczenko (2014)
determined that this pair shares common proper motion. From colors,
spectral types for the primary and secondary appear to be about K0 and
G8V, repectively; distances are 640 and 870 pc, masses about 0.79 and
0.81 Msun. Krw2014a
