330 Adalberta, provisional designation A910 CB, is a stony asteroid from the inner regions of the asteroid belt, approximately 9.5 kilometers in diameter. It is likely named for either Adalbert Merx or Adalbert Krüger. It was discovered by Max Wolf in 1910. In the 1980s, the asteroid's permanent designation was reassigned from the non-existent object 1892 X.
Adalberta was discovered on 2 February 1910, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany.
Previously, on 18 March 1892, another body discovered by Max Wolf with the provisional designation 1892 X was originally designated 330 Adalberta, but was subsequently lost and never recovered (also see Lost minor planet). In 1982, it was determined that Wolf erroneously measured two images of stars, not asteroids. As it was a false positive and the body never existed, the name Adalberta and number "330" was then reused for this asteroid, A910 CB. MPC citation was published on 6 June 1982 (M.P.C. 6939).
The S-type asteroid orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 11 months (1,416 days). Its orbit has an eccentricity of 0.25 and an inclination of 7° with respect to the ecliptic.Adalberta's observation arc begins with its official discovery observation at Heidelberg in 1910.
