(20222) Benseguane Main-belt Asteroid
Discovered on 30 April 1997 by LINEAR at Socorro.
Selma Benseguane (b. 1994) is an Algerian astronomer, working on the link between cometary activity and surface morphology, showing that pits at the surface of comets cannot be formed on their current orbit but might result from processing in the giant planet region when they were Centaurs.Naming citation (WGSBN Bull. 6, #11, 11), IAU / Minor Planet Center, via NASA/JPL
