docs: Twenty two observations of the Dwarf planet Ceres as observed by Giueseppe Piazzi and published in the September edition of Monatlicher Correspondenz in 1801. These were the measurements used by Gauss to fit a model of the planets orbit through which the planet was recovered three months later.
