[漢羅] Mimas:有大隕石坑 ê 細粒衛星

毋管是 siáng kah Mimas 相碰,攏會 kā 伊挵甲 giōng 欲碎--去。 這是 土星 一粒上細粒 ê 球形衛星面頂,其中一擺 上大相碰產生 ê 隕石坑分析了後發現,若是閣較強一點仔 ê 相碰, to̍h 會 kā Mimas 規粒挵碎。 這个大隕石坑是 tī 1789 年 tī Mimas 發現 ê,叫做 Herschel,是用 William Herschel 爵士 ê 名號--ê。 這粒有 130 公里闊 ê 隕石坑 to̍h tī 遮。 低質量 ê Mimas 產生 ê 表面重力,拄仔好強到有法度結做一粒 球形天體,嘛拄仔好弱到有法度產生這款大型 ê 表面結構。 Mimas 大部份 ê 成份是水冰 kah 一寡岩石。 所以講伊是一粒大粒 ê 垃圾雪球,實在是真鬥搭。 這張影像是 Casiini 機器人太空船 tī 2010 年 踅土星 leh 行 ê 時陣,飛過 Mimas 上近彼陣翕 ê。

[English] Mimas: Small Moon with a Big Crater

Whatever hit Mimas nearly destroyed it. What remains is one of the largest impact craters on one of Saturn's smallest round moons. Analysis indicates that a slightly larger impact would have destroyed Mimas entirely. The huge crater, named Herschel after the 1789 discoverer of Mimas, Sir William Herschel, spans about 130 kilometers and is featured here. Mimas' low mass produces a surface gravity just strong enough to create a spherical body but weak enough to allow such relatively large surface features. Mimas is made of mostly water ice with a smattering of rock - so it is accurately described as a big dirty snowball. The featured image was taken during the closest-ever flyby of the robot spacecraft Cassini past Mimas in 2010 while in orbit around Saturn.
