The group was headed by Franz Xaver von Zach, editor of the Monatliche Correspondenz. While they did not discover Ceres, they later found several large asteroids. Piazzis Book Della scoperta del nuovo pianeta Cerere Ferdinandea outlining the discovery of CeresOne of the astronomers selected for the search was Giuseppe Piazzi at the Academy of Palermo, Sicily. However, before receiving his invitation to join the group, Giuseppe Piazzi discovered Ceres on 1 January 1801. He was searching for a star listed by Francis Wollaston as Mayer 87, because it was not in Mayers zodiacal catalogue in the position given.

Instead of a star, Piazzi found a moving star-like object, which he first thought was a comet. Piazzi observed Ceres a total of 24 times, the final time on 11 February 1801, when illness interrupted his observations. He ann...More: http: //booksllc.net/?id=5595163
