 808 Merxia is the namesake of the Merxia family of asteroids that share similar orbital elements and physical properties.The members of this family, including 808 Merxia, most likely formed from the breakup of a basalt object, which in turn was spawned from a larger parent body that had previously undergone igneous differentiation.Other members of this family include 1662 Hoffmann and 2042 Sitarski.
