文字稿
In January and February, stargazers around the world can see six planets across the night sky at the same time.
在今年一月和二月间，全世界的观星者都能看到六颗行星同时出现在夜空中的景象。
Venus, Mars, Jupiter and Saturn are visible to the naked eye, while Uranus and Neptune can be seen through a telescope.
其中，金星、火星、木星和土星都是肉眼可见的，而天王星和海王星则需要借助望远镜观察。
NASA, the US space agency, wrote in an article that "These multi-planet viewing opportunities aren't super rare, but they don't happen every year."
美国国家航空航天局在一篇文章中写道：“能同时观察到多颗行星的机会并不十分罕见，却也不是每年都会出现”。
These events are sometimes called an 'alignment' of the planets.
这一天文现象也会被称为行星的 “连珠” 现象。
But planets aren't really lining up next to each other like this.
但这些行星并不是真的像这样紧挨着连成一线。
All planets orbit the Sun on a flat plane but at different speeds and distances.
太阳系各行星都在同一平面上围绕太阳运行，但运行速度和与太阳的距离各不相同。
When they reach specific points in their orbits, they create an illusion of alignment seen from the Earth.
当它们达到运行轨道中的特定位置时，就形成了从地球上看时像是排成了一线的假象。
So, while such an alignment may not be special, it's less common seeing four or five bright planets at once.
所以，虽然像这样的 “连珠” 现象并不罕见，但能同时看到四颗或五颗明亮的行星比较难得。
