1240 Centenaria, provisional designation 1932 CD, is a main-belt asteroid discovered on February 5, 1932, by astronomer Richard Schorr at Bergedorf Observatory in Hamburg, Germany. The asteroid measures about 59 kilometers in diameter, it orbits the Sun in the outer main-belt at a distance of 2.4–3.4 AU once every 4 years and 10 months (1,773 days). Its orbit has an eccentricity of 0.17 and an inclination of 10° with respect to the ecliptic.of 2.4–3.4 AU every 4.86 years and is inclined by 10 degrees to the ecliptic.[1]

It was named Centenaria to celebrate the 100th anniversary of the discovering observatory on October 31, 1933.[2]
