Ceres
planit kerdhil ing Tata Surya
1 Ceres (simbol: .svg){kind=small}
)[15] punika satunggilng planit kerdhil wonten ing sabuk asteroid. Ceres kapanggihaken ing tanggal 1 Januari 1801 déning Giuseppe Piazzi. Wiwitanipun nalika kapanggih Ceres kaanggep satunggiling planit, 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 "planit kerdhil".
