1 Ceres punika satunggilng planet kerdhil wonten ing sabuk asteroid. Ceres kapanggihaken ing tanggal 1 Januari 1801 déning Giuseppe Piazzi. Wiwitanipun nalika kapanggih Ceres kaanggep satunggiling planèt, nanging setengah abad salajengipun lan antawisipun 150 taun salajengipun, Ceres dipunklasifikasi dados satunggiling asteroid. Ing tanggal 24 Agustus 2006, Persatuan Astronomi Internasional mutusaken kanggé ngéwahi status Ceres dados "planet kerdhil".
Ceres anggadhahi massa 9,45±0,04 × 1020 kg. Kanthi dhiameter kirang langkung 950 km, Ceres punika benda angkasa paling ageng ing sabuk asteroid utami.
