| 330 Adalberta (A910 CB) Discovered 1910-Feb-02 by Wolf, M. at Heidelberg |
| This planet was alleged to have been discovered 1892 Mar. 18 by M. Wolf at Heidelberg with the provisional designation 1892 X. Only one more position Mar. 20 was obtained, and from the resulting circular elements this object was never observed again. In 1982 R. M. West, C. Madsen, and L. D. Schmadel showed that these observations refer to galactic stars, and that 1892 X does not exist. Later in that year the designation 330 Adalberta was assigned to planet A910 CB, which had earlier been incorrectly identified with 783 Nora, and now newly numbered. |
