Ceres (1 Ceres in le catalogo del Centro de Planetas Minor statounitese; symbolo: &sq=Envato&lang=ia&file=File:Ceres_symbol_(bold).svg){kind=small}
)[7] es le plus parve planeta nano in le systema solar, e le sol situate in le principal cinctura de asteroides.
Illo esseva discoperite le 1 de januario 1801 per Giuseppe Piazzi. Con un diametro de circa 950 km, Ceres es certo le corpore le plus grande e plus massive in le cinctura de asteroides, constituente circa un tertio del massa total de illo. Observationes recente ha revelate que illo es spheric, in contrasto con le figuras irregular de asteroides plus parve con minus gravitate.
