(18242) Peebles Main-belt Asteroid
Discovered on 29 September 1973 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T. at Palomar.
Princeton theoretical cosmologist Jim Peebles (b. 1935) plays a central role in the understanding of the evolution and structure of the universe. His studies of the evolution of matter in the earliest moments of the universe were critical in the establishment of the Big Bang theory as a widely accepted hypothesis.Naming citation (20040306/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
