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 \arcdeg . 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 55733AU from GJ 282AB , NLTT 18149 ranks among the widest physical companions known .
