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 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.
It was named after the mother of the discoverer, Celestia MacFarland Whipple.
