Often called an elusive planet, Mercury spends most of its time hidden by the overwhelming glare of the Sun.

水星常被稱為「難以捉摸的行星」,大部分時間都隱藏在太陽耀眼的光芒之中。

nounMercury
nounSun

Because it orbits so close to our star, it never strays more than 28 degrees from it, meaning it can only be seen during the short periods of twilight at dawn or dusk.

由於它繞行太陽的軌道極其靠近恆星,與太陽的夾角從不超過28度,這意味著它只能在黎明或黃昏的短暫晨昏蒙影時段被看見。

我們目前正接近「大距」,這是指從地球觀測時,水星運行至與太陽之間距離最遠的時刻。

This creates a wider window for viewing, as the planet sits higher above the horizon.

這創造了更寬闊的觀測窗口,因為水星此時在地平線上的位置較高。

If you are struggling to find it, look for nearby guideposts like the crescent Moon or brighter planets like Venus.

如果您難以找到它,可以尋找附近的指標,例如眉月或像金星一樣更明亮的行星。

Take advantage of this fleeting sweet spot, as Mercury is truly a world that spends most of its time lost in the shadow of the Sun.
