Heavily - cratered callisto is only a little smaller than ganymede and , like europa , might be hiding a subterranean ocean 布滿隕石坑的克利斯托星僅僅稍小于格尼梅德星,它可能與歐羅巴星相似,蘊藏著地下海洋。

Callisto was another maiden who excited the jealousy of juno , and the goddess changed her into a bear 卡利斯忒是另一個引得朱諾妒火中燒的少女,朱諾把她變作一頭熊。

And we believe there are water lakes under the icy surface of europa and callisto 不少科學家相信在歐羅巴和卡利斯托的冰層下有液態湖的存在。
