(330) Adalberta is an asteroid of the inner main asteroid belt , which was discovered on February 2, 1910 by Max Wolf from the Heidelberg-Königstuhl State Observatory.

designation

Originally another object that Max Wolf had discovered photographically on March 18, 1892 and had the provisional designation "1892 X" was given the name (330) Adalberta. Only two positions of this object could be determined, based on which it could never be observed again later. In 1982 RM West, C. Madsen and Lutz D. Schmadel were finally able to show that the observed object was in fact stars in our galaxy. In the same year, the designation (330) Adalberta was reassigned to another object, which had also been discovered by Max Wolf, was given the provisional designation "A910 CB" when it was discovered and was mistakenly believed to be identical to (783) Nora .

Max Wolf named the asteroid in honor of his father-in-law Adalbert Merx .

Orbit

Adalberta moves at a distance of 1.8 ( perihelion ) to 3.1 ( aphelion ) astronomical units in 3.9 years around the sun . The orbit is inclined 6.8 ° to the ecliptic , the orbital eccentricity is 0.25.

Physical Properties

The diameter of Adalberta is about 9 kilometers. It rotates on its own axis in 3.5 hours.
