1252 Celestia, provisional designation 1933 DG, is a stony Palladian asteroid from the central region of the asteroid belt, discovered on 19 February 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]

This minor planet was named after the mother of the discoverer, Celestia MacFarland Whipple.^[3]
