1252 Celestia, provisional designation 1933 DG, is a stony main-belt asteroid discovered on February 19, 1933, by American astronomer Fred Whipple at Oak Ridge Observatory[2] operated by the Harvard-Smithsonian Center for Astrophysics at Massachusetts, United States. The S-type asteroid measures about 17 kilometers in diameter, rotates once every 10.6 hours and is heavily tilted towards the ecliptic by almost 34 degrees.[1]
It was named after the mother of the discoverer, Celestia MacFarland Whipple.[3]
