(12893) Mommert Main-belt Asteroid
Discovered on 26 August 1998 by ODAS at Caussols.
Michael Mommert (b. 1982) has analysed Herschel and Spitzer space telescope observations of transneptunian and near-Earth objects, finding further evidence for links between these populations. He has provided insight into the physical properties of the Plutinos and the cometary component of the NEO population.Naming citation (MPC batch dated 2013-09-19), IAU / Minor Planet Center, via NASA/JPL
