(8753) Nycticorax is an asteroid of the main inner 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 Italian astronomer Vincenzo Zappalà used a hierarchical cluster analysis in a publication from 1995 (et al.) To extrapolate the asteroid's membership of the Nysa family, a group of asteroids named after (44) Nysa . The group is also called the Hertha family, after (135) Hertha .
(8753) Nycticorax is named after the night heron , whose scientific name is Nycticorax nycticorax . At the time the asteroid was named on February 2, 1999, the night heron was on the Dutch Red List of Endangered Species .
