(9252) Goddard is an asteroid of the main outer belt that was discovered on October 17, 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 mean diameter of the asteroid was roughly calculated to be 11.774 km (± 3.041).
(9252) Goddard was named on April 2, 1999 after the American rocket pioneer Robert Goddard (1882–1945). As early as 1964, a lunar crater on the eastern front of the moon was named after Robert Goddard: lunar crater Goddard .
