A stable time-fuel optimal spiral orbit for the rendezvous of an inspector satellite is put forward.
本文设计了一条稳定的燃料-时间优化回收轨道。
In this case, the orbit of the rotating asteroid will very slowly spiral toward the sun.
在这种情况下，旋转小行星的轨道将非常缓慢地向太阳旋转。
In this case, the orbit of the rotating asteroid will very slowly spiral in toward the sun.
在这样的情况下，旋转小行星的运行轨道将非常缓慢地向朝着太阳的方向盘旋。
Their stars orbit the galactic center, like those in the disks of spiral galaxies, but they do so in more random directions.
这些恒星象螺旋星系中的恒星一样围绕星系中心运转，但在方向上更随机一些。
If the satellite has an elliptical orbit the result is a spiral wave a miniature version of the pinwheel pattern of our galaxy.
如果卫星的轨道是椭圆的，就会产生螺旋波，就像是银河系纸风车形状的缩影。

As these tiny stellar remnants orbit one another, calculations show that they should lose energy and spiral together.
一旦这些微小的恒星遗存互相围绕运行，计算表明它们将失去能量盘旋接近。
Skip to next paragraph If nature is left to its own devices, about 7.59 billion years from now Earth will be dragged from its orbit by an engorged red Sun and spiral to a rapid vaporous death.
如果让大自然自己运行，从现在算起约75.9亿年后，地球将因火红滚沸的太阳的引力而脱离轨道，飞旋并很快蒸发消亡。
