G 112-29 (=NLTT 18149): a very wide companion to GJ 282 AB with a common proper motion, common parallax, common radial velocity, and common age.

Abstract (from CDS):
We have made a search for common proper motion (CPM) companions to the wide binaries in the solar vicinity. We found that the binary GJ 282AB has a very distant CPM companion (NLTT 18149) at a separation s = 1°.09. Improved spectral types and radial velocities are obtained, and ages determined for the three components. The Hipparcos trigonometric parallaxes and the new radial velocities and ages turn out to be very similar for the three stars, and provide strong evidence that they form a physical system. At a projected separation of 55,733 AU from GJ 282AB, NLTT 18149 ranks among the widest physical companions known.
