Pandora is the fourth of Saturn's known satellites:
orbit: 141,700 km from Saturn
diameter: 84 km (114 x 84 x 62)
mass: 2.2e17 kg
In Greek mythology Pandora was the first woman, bestowed upon humankind by Zeus as a punishment for Prometheus' theft of fire. Entrusted with a box containing all the ills that could plague people, she opened it out of curiosity and thereby released all the evils of human life; wife of Epimetheus.
Discovered by Collins and others in 1980 from Voyager photos.
Pandora is the outer shepherd satellite of the F ring. The image at right shows both Pandora, the faint F ring, Prometheus and part of the A ring. (Click the image for a much finer image from Cassini)
Craters formed on this object by impacts appear to be covered by debris, a process that probably happens rapidly in a geologic sense. The grooves and small ridges on Pandora suggest that fractures affect the overlying smooth material.
Pandora 是土星已知衛(wèi)星中距其第四近的一顆：
公轉(zhuǎn)軌道：距土星 141,700 千米
衛(wèi)星直徑：84 千米（114×84×62）
質(zhì)量：2.2e17 千克
在希臘神話中，潘多拉是由于普羅米修斯偷火種，被宙斯派來懲罰人類的第一個(gè)女人。她被要求保管一只盒子，里面裝著所有能夠危害人類的災(zāi)禍。她出于好奇找開了這個(gè)盒子，因此釋放了所有人類生活中的罪惡。潘多拉是Epimetheus的妻子。
這顆衛(wèi)星于1980年被Collins和他的同伴從旅行者號(hào)的照片上發(fā)現(xiàn)。
土衛(wèi)十七是F光環(huán)外的牧羊衛(wèi)星。從右邊的圖片上可看到土衛(wèi)十七和不明顯的F光環(huán)，土衛(wèi)十六及A光環(huán)的部分。
這顆衛(wèi)星上的隕石坑比附近的土衛(wèi)十六上的更大，土衛(wèi)十七至少有兩個(gè)直徑大約30千米的大隕石坑。但是它沒有長(zhǎng)條形的山脈和峽谷。
