808 Merxia

It forms the namesake for the Merxia family of asteroids that share common orbital elements and physical properties.

The spectrum of this object indicates that it is an S-type asteroid with both low and high calcium forms of pyroxene on the surface, along with less than 20% olivine.

The high-calcium form of pyroxene forms 40% or more of the total pyroxene present, indicating a history of igneous rock deposits.

This suggests that the asteroid underwent differentiation by melting, creating a surface of basalt rock.

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.
