(11763) Deslandres is an asteroid of the main outer belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The asteroid is a member of the Koronis family, a group of asteroids named after (158) Koronis . The ageless (not osculating ) orbital elements of (11763) Deslandres are almost identical to those of the larger asteroids (6276) Kurohone and the smaller asteroids (23808) Joshua Hammer , (38416) 1999 RV 213 , (61422) 2000 QN 15 and (198,804) 2005 EW 180 . The size comparison is based solely on the absolute brightness , since the diameters of the celestial bodies are not known.
(11763) Deslandres was named on September 26, 2007 after the French astronomer Henri-Alexandre Deslandres (1853–1948). A lunar crater in the south of the front of the moon was named after Deslandres as early as 1948 : Deslandres lunar crater .
