1 Ceres (hû-hō: )^[17] 是 (sī)1粒 (lia̍p)踮 (tiàm)佇 (tī)小惑星帶 (sió-he̍k-chheⁿ-toà)的 (ê)矮惑星 (é-he̍k-chheⁿ)，發現人 (hoat-hiān-jîn)是Giuseppe Piazzi，佇1801年 (nî)。Ceres是羅馬 (Lô-má)查某 (cha-bó͘)神明 (sîn-bêng)的名 (miâ)。

19世紀 (sè-kí)侵 (chhím)發現 (hoat-hiān)的時 (sî)，人 (lâng)掠準 (lia̍h-chún)伊 (i)和 (hām)其他 (kî-thaⁿ)的惑星 (he̍k-chheⁿ)相 (sio)siâng，所以 (só͘-í)共 (kā)伊當做 (tòng-chò)1粒惑星。尾仔 (Boé--á)卡 (khah)了解 (liáu-kái)伊的性質 (sèng-chit)了後 (liáu-aū)，就 (tō)共列 (lia̍t)做 (chò)小惑星 (sió-he̍k-chheⁿ)。雖罔 (Sui-bóng)1 Ceres直徑 (ti̍t-kèng)才 (chiah)950km，伊實在 (si̍t-chāi)是太陽系 (Thài-iông-hē)13萬 (bān)粒小惑星當中 (tang-tiong)，上 (siōng)蓋 (kài)大 (toā)粒，質量 (chit-liōng)上濟 (chē)，形 (hêng)象 (siōng)îⁿ的1粒，會使 (ē-sái)講 (kóng)小惑星帶有 (ū)3份 (hūn)1个 (ê)質量佇伊遐 (hia)。因為 (In-ūi)按呢 (án-ne)， 2006年8月 (goe̍h)天文學界 (thian-bûn-ha̍k-kài)閣 (koh)共伊改 (kái)熱 (lia̍t)做1粒 "矮惑星"。

↑ The value given for Ceres is the mean moment of inertia, which is thought to better represent its interior structure than the polar moment of inertia, due to its high polar flattening.^[8]
