n.远日点(远核点)
But it's not that simple either, because the dates of the perihelion and aphelion are also shifting. 但这并不是简单的一件事情,因为近日点和远日点的日期都会变换。
Otherwise difficult to notice, the change in the Sun's apparent diameter between Perihelion and Aphelion is clear. 我们很难用肉眼看出近日点和远日点太阳视直径的变化，但在这张图上显而易见。
The point in the orbit nearest the sun is called perihelion, while the point farthest is called aphelion. 在轨道上最接近太阳的点被称为近日点，而最远离太阳的点被称为远日点。
Last year, on July 4, 2008, the Earth at aphelion was some 8,000 miles more distant, at 94,513,144 miles. 去年，2008年7月4日，地球在远日点的距离大概远了8,000英里，甚至更多些，达到94,513,144英里。
Astronomers call this point aphelion, and, at aphelion we're about three million miles farther from the sun than we will be six months from now. 宇航员叫这点为远日点，在远日点我们距日大约有3亿英里比我们。
