[漢羅] 土衛一 Mimas ê Herschel 隕石坑

土衛一 Mimas 是土星 ê 細粒衛星，伊 ê 直徑才 400 公里闊，毋閣伊有一个直徑 130 公里大 ê Herschel 隕石坑，是規个太陽系內底上大 ê 隕石坑。 Cassini 機器人太空船 tī 2010 年踅土星咧行。 伊飛過這粒小型 冰世界 1 萬公里近 ê 時陣，有紀錄著 這个不得了 ê 景色：遮爾細粒 ê 衛星，有遮爾大 ê 隕石坑。 這个影像資料利用假色加強對比，而且較倚咱這爿、去予舂甲較深 ê 地形，有用小可仔無仝色做記號。 按呢會當予 Herschel 隕石坑，展示閣較清楚 ê 地景。 無仝色應該是地表 ê 組成成份無仝，這可能是因為 土衛一 Mimas 以前 捌去予舂甲糜糜卯卯。 是講 土衛一 Mimas 若是拄著 比挵出這个直徑 130 公里大 閣較大 ê 衝擊事件，可能會予這粒 土星 ê 細粒衛星，規粒 毀滅去。

[English] Herschel Crater on Mimas

Mimas, small 400 kilometer-diameter moon of Saturn, is host to 130 kilometer-diameter Herschel crater, one of the larger impact craters in the entire Solar System. The robotic Cassini spacecraft orbiting Saturn in 2010 recorded this startling view of small moon and big crater while making a 10,000-kilometer record close pass by the diminutive icy world. Shown in contrast-enhanced false color, the image data reveal more clearly that Herschel's landscape is colored slightly differently from heavily cratered terrain nearby. The color difference could yield surface composition clues to the violent history of Mimas. Of course, an impact on Mimas any larger than the one that created the 130-kilometer Herschel might have destroyed the small moon of Saturn.
