Also known as axial tilt or obliquity.

也被称为转轴倾角(axial tilt)或倾角(obliquity)。

This is known as the Earth's axial tilt, or obliquity.

这也被称作“轴倾角”。

And that axial tilt of the Earth is one of the main reasons for the seasons.

倾斜的地轴是造成四季的主要原因之一。

However, perhaps the most catastrophic effect that would happen without a moon would be the extreme change in Earth's axial tilt.

然而，在没有月球的情况下，最具灾难性的影响可能是地球轴心倾角的极端变化。

A full-fledged satellite maintains the stability of the Earth's axial tilt, but a significantly lighter moon would not be able to accomplish this task.

一个饱满的卫星可以保持地球轴向倾斜的稳定性，但一个明显较轻的月球将无法完成这一任务。

The second movement involved in the hypothesis has to do with axial tilt.

假设中涉及的第二个运动与轴向倾斜有关。

Mercury doesn't have much of an axial tilt or much of an atmosphere, so no seasons for you either.

水星没有太多的轴向倾斜或太多的大气层，所以你也没有季节。

That represents Earth's axial tilt, which astronomers call its obliquity, relative to the plane of its nearly circular orbit around the sun.

这代表地球相对于其围绕太阳的近圆形轨道平面的轴倾斜，天文学家称之为倾斜角。

To figure out which idea is most likely, we have to know more about Venus's early dynamics, specifically its rotation rate and axial tilt.

为了找出最有可能的想法，我们必须更多地了解金星的早期动力学，特别是它的自转速率和轴向倾斜。

So the Earth's axial tilt partially explains why the Sun changes positions in the sky and the analemma's length represents the full 46.8 degrees of the sun's declination throughout the year.

所以地球的自转轴的倾斜能够部分解释太阳在天空中位置变化的原因，地球仪的8字曲线的长度也代表了太阳在一整年倾斜的46.8°的角度。
