Janus,   the moon that contributes to the resonance, switches orbital positions every four years  with its close neighbour moon, Epimetheus.

雅努斯（Janus）是负责共振卫星，每四年近邻卫星埃庇米修斯（Epimetheus）交换轨道位。

Some researchers are now starting to compile a massive data set that includes the best possible information on where everything is in orbit.

An annular eclipse is a solar eclipse that occurs when the Earth's orbit brings it relatively close to the sun at the same time that the moon's orbit takes it relatively far from the Earth.

日环食是日食一种，指当地球在相对接近太阳轨道位，而此同时月球在相对远离地球轨道位，就会生日环食。

As asteroids on either side of this band orbit the sun, they pass Jupiter and get a little extra gravitational pull, but that pull comes at a different place with each orbit, so it kind of just averages out over time.

当这条带两侧小行星绕太阳运行时，们会经过木星并获得一点额外引力， 但这种引力在每个轨道上位不同， 所以会随着时间推移而平均化。
