Well the earth is rotating while simultaneously revolving around the sun.

其实地球在自转的同时也绕太阳公转。

In summary, the tilt of our planet has a much greater significance compared to the variations in distance to the Sun.

总之，地球自转轴的倾斜对气候的影响比与太阳的距离造成的影响大更多。

And if we look at the Sun-Earth system from afar we find that the Earth's axis maintains the same orientation regardless of its position in its orbit around the Sun.

如果从远处看一下太阳与地球的关，可以发现地球的自转轴始终保持相同的方向，无论它在轨道位置的哪一个地点。

It's not only the biggest planet. Scientists say Jupiter is also the fastest spinning and completes a day in less than 10 hours.

木星不仅是最大的行星，家表示，也是自转速度最快的行星，一天的自转周期还不到10个小时。

When a planet is that close to its star, its rotation becomes locked.

一颗行星离它所环绕的恒星近时，它的自转就会固定。

Due to the Earth's spin, the jet streams form then move from west to east, each one traveling on average at more than 100 miles per hour.

由于地球自转，高速气流由西向东移动，每条气流的平均时速超过了100英里。

One turn on the Earth's axis takes 24 hours — that's what makes one day.

地球自转一周，需要24小时也就是一天。

This is really just a reflection of the Earth spinning, of course.

然，这只是地球自转的一种反映。

Let's just leave our planet to spin the way it does.

还是让地球继续自转吧。

Earth rotates at about a thousand miles per hour, but new research published in " Nature Geoscience" says that the Earth's inner core may have actually stopped turning and now might start to spin in reverse.

地球以每小时1000英里的速度自转，但《自然地球》上发表的一项新研究却认为，内地核实际上可能已经停止转动，并开始了反向旋转。

24 hours makes one day that's just one time that I'm spun.

的一天是 24 小时，那是自转一圈的时间。

It takes 243 Earth days for Venus to complete one full rotation.

金星自转一圈需要243个地球日。

A large mass in turn entails two more unpleasant surprises: the accelerated rotation of the planet around its axis and a much higher temperature.

行星绕轴加速自转和更高的温度。

Not to mention, the Earth's spin may increase, making days only hours long.

更不用说地球自转的速度也将加快，一天可能只有几个小时。

Earth spins on its axis currently at 23.4 degrees.

地球目前的轴心自转为23.4度。

Telltale tweaks to the spins of dead stars called pulsars scattered throughout the Milky Way.

散布在银河中的、被称为“脉冲星”的死亡恒星，其自转发生了微妙的变化。

Phase two, activating the Torque Engines encircled along the equator to stop Earth's rotation.

第二阶段 启动绕赤道的转向发动机 驱使地球停止自转。

We forgot to put the rotation of the Earth into the equation.

忘了在方程式中加入地球自转了。

Now, some people were also afraid it could tilt the earth on its axis in a dangerous way or cool down Europe to the point there would be a new Ice Age.

现在，有些人还担心它可能会以危险的方式导致地球自转轴倾斜，或者使欧洲温度下降，从而引发新的冰河时期。

This might start with outposts in space, transition to infrastructure and industries near the home planet, move on to colonies, and end with terraforming other planets, by changing their atmosphere, their rotation, or position.

这可能会从建立太空前哨，进而将母星附近的基础设施和工业区变成殖民地开始，并以改造其他行星的大气、自转或位置告终。
