What is aphelion?

什么是远日点?

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。

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。

There are times when it is more elliptical than it is now, so the difference in solar radiation received at the perihelion and aphelion will be greater.

在某些时期地球的轨道比现在更接近椭圆,因此在近日点和远日点处接受太阳辐射差别就更大。

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。

The point where the Earth is closest to the sun is called perihelion.The point where the Earth is farthest from the sun is called aphelion.

地球距离太阳最近的那点称为近日点，最远的点称为远日点。

Slightly more solar energy is received when the Sun and Earth are closest (the perihelion) than when they are farthest apart (the aphelion).

太阳和地球的距离最近(近日点)时,所接收的太阳能要比距离最远(远日点)时接收的稍多一点。

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。

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。

Explanation: This year Aphelion, the point in Earth's elliptical orbit when it is farthest from the Sun, occurs tomorrow, July 4th.

说明：地球将在明天（7月4日）经过今年的远日点，也就是地球椭圆轨道上离太阳最远的那一点。

This total solar eclipse occurred near Aphelion, the point in Earth's elliptical orbit farthest from the Sun, and so the Sun was near its smallest apparent size.

这次日全食发生时，在太阳处于远日点附近，也就是地球轨道上离太阳最远的一点，所以太阳的视尺寸接近最小；

aphelion n.

远日点；

aphelion passage

通过远日点

Atens: semimajor axes less than 1.0 AU and aphelion distances greater than 0.983 AU;

阿托恩：半长轴小于1个天文单位，远日点大于0。983天文单位；
