orbital velocity

基本解釋

If you want to escape from this, you will need a speed which is the square root of two times larger than that orbital velocity.
如果想要逃離這里，你將需要一個速度,是軌道速度2倍大的,平方根。
Astronauts aboard the ISS see 16 sunrises and sunsets per day due to their high orbital velocity (greater than 28,000 km per hour).
每天，宇航員在高速（每小時大于28000千米）運(yùn)行的軌道上能看到16次日出和日落。
Whether you have a very light object or a very heavy satellite, they have the same velocity in orbit if they are at the same distance, and they have the same orbital period.
不論你有個很輕的,物體還是很重的衛(wèi)星,如果它們距離相同且,在軌道運(yùn)動時間,相同，則速度一樣。

the velocity required by a spacecraft, satellite, etc, to enter and maintain a given orbit
