AI overview

Eukelade is a small moon of Jupiter that orbits backward relative to the planet's rotation, discovered in 2003 by astronomers at the University of Hawaiʻi. It matters because studying such irregular satellites helps scientists understand Jupiter's complex moon system and the history of collisions and gravitational interactions in the early solar system.

木衛四十七()(Eukelade,发音为/jʊˈkɛlədiː/ ew-KEL-ə-dee,或是希臘文的Ευκελάδη),是木星的逆行不規則衛星。它是被夏威夷大學由斯科特·谢泼德領導的團隊在2003年發現的,標準的臨時名稱是S/2003 J 1。 木衛四十七的直徑大約4公里,以平均234億8400萬公里的距離,對黃道傾斜164° (對木星赤道傾斜165°),在逆行的方向,0.2829的離心率繞著木星公轉。 它在2005年3月被命名為,有些希臘作家描述它是繆斯之一,因此是宙斯 (木星) 的女兒。 木衛四十七屬於加爾尼群,是不規則的逆行衛星,以大約165°的傾角和範圍在2300萬至2400萬公里的距離環繞著木星。
