Adrastea is the second of Jupiter's known satellites:
orbit: 129,000 km from Jupiter
diameter: 20 km (23 x 20 x 15)
mass: 1.91e16 kg
Adrastea, the distributor of rewards and punishments, was the daughter of Jupiter and Ananke.
Discovered by graduate student David Jewitt (working under Danielson) in 1979 (Voyager 1).
Metis and Adrastea orbit inside the synchronous orbit radius and inside the Roche limit. They may be small enough to avoid tidal disruption but their orbits will eventually decay.
Adrastea is one of the smallest moons in the solar system.
Adrastea 是已知衛(wèi)星中離木星第二近的一顆:
公轉(zhuǎn)軌道:距木星 129,000 千米
衛(wèi)星直徑:20 千米(23×20×15)
質(zhì)量:1.91e16 千克
Adrastea是獎(jiǎng)賞和懲罰的分配者,是朱比特(木星)與Ananke(木衛(wèi)十二)的女兒。
它是研究生David Jewitt(在丹尼爾森手下工作)于1979年發(fā)現(xiàn)(旅行者1號(hào))。
木衛(wèi)十六與木衛(wèi)十五的公轉(zhuǎn)軌道處在同步公轉(zhuǎn)軌道半徑之內(nèi),并在Roche極限之內(nèi)。它們太小以致于能避免引潮力把它們拉碎,但它們的軌道將逐漸變小,最終墜入木星。
木衛(wèi)十五是太陽系中最小的衛(wèi)星之一。
