| Abstract: | The original observational records were used in a new reduction of early meridian observations of Ceres and Pallas. Later observations underwent systematic corrections. Normal places represent the single observations of the interval from 1802 to 1970. A new value for the mass of Ceres equal to (5.9 +/- 0.3)*10-10 solar mass resulted from a differential correction of the orbit of Pallas. The reversion of the problem allowed the derivation of a preliminary value for the mass of Pallas from the observations of Ceres. This value has a comparatively large relative uncertainty, because the mass of Pallas equals only about one fourth or one fifth of the mass of Ceres. |
