伊阿珀托斯-
土星的菲比卫星的运行轨道也在该环内，并且倾斜角度也相同，所以它很可能也是伊阿珀托斯呈现双色的另一个原因。
Saturn 's moon Phoebe orbits within the ring and at the same inclination , so it is very likely that it is the culprit .

虽然它如此弥散，只能被红外线检测到，但它很可能是双色卫星——伊阿珀托斯形成的原因。
It is so diffuse that it can only be detected in infrared , but it may be the reason behind the two-toned moon , Iapetus .

宇宙尘埃从菲比卫星散射出来并落到更大的伊阿珀托斯星周围。而伊阿珀托斯在这巨大新环的边缘运转，每次伊阿珀托斯经过菲比卫星，这些物质就在伊阿珀托斯的赤道上不断积累。
Dust disperses from Phoebe and falls onto the larger Iapetus , which orbits on the edge of this colossal new ring . Every time Iapetus passes through it , matter collects on its equator .
