mass in earth orbit

基本解释

So the kinetic energy of the Earth * in orbit equals one-half mass So I take this equation and I square it.
所以地球的动能,=1/2m地,用这个等式，开平方。
We are coordinating our efforts with millions of Ships now in Earth's Orbit and preparing for mass decloakings.
目前我们正和驻扎在地球轨道上的数以百万计的飞船协调行动，为大规模的揭幕做准备。
Two moons may have once circled the Earth in the same orbit until a slow-motion collision blended the larger object with a sister satellite one-thirtieth its mass to create the Moon we see today.
地球上可能原本拥有两个月亮沿同一轨道运行，后来发生了一次慢速碰撞，较大的一个“月亮”和约为其质量1/30的姊妹“月亮”合二为一，形成我们现在看到的月亮。
