8463 Naomimurdoch           Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
Naomi Murdoch (b. 1984) completed her Ph.D. at The Open University, United Kingdom in 2012. Using microgravity flight experiments and numerical modeling, she investigated the behavior of granular material under minor-planet-like low-gravity surface conditions.
