RED 22 M3 star is ~21" from K0 dwarf HD 56168 = HIP 35628 = 2MASS
J07210672+6739425. The Hipparcos distance for the M dwarf 27pc, the
very different proper motions suggest the stars appear unrelated. Red2007a
JNN 55 BC: In addition to the close binarity discovered in the AstraLux data,
there is a star at 21" separation (HIP 35628), but due to its very
different proper motion, it is likely physically unrelated to the Red2007a
2MASS J07210894+6739590 system (Reid et al. 2007). Jnn2012
