    8日天宇將上演月掩金星

    原標(biāo)題:8日天宇將上演月掩金星

      11月8日,天宇將上演月掩金星罕見(jiàn)天象,屆時(shí),“太白”和“嫦娥”會(huì)在大白天玩起“捉迷藏”游戲。

      金星,我國(guó)古代稱(chēng)之為“太白”,通常情況下,它是除太陽(yáng)和月亮外全天最亮的天體。月掩金星是指月球運(yùn)行至地球與金星之間,三者排成一條直線(xiàn),屆時(shí)月球?qū)?huì)在金星前面“路過(guò)”。由于月球的視直徑遠(yuǎn)大于金星的視直徑,因此在“路過(guò)”的時(shí)候會(huì)把金星完全擋住。本次月掩金星,我國(guó)東北地區(qū)及朝鮮半島、日本地區(qū)可見(jiàn),但發(fā)生時(shí)恰逢白天。具體到我國(guó)東北地區(qū)是在中午,由于天空非常明亮,觀測(cè)難度很大,需要借助雙筒望遠(yuǎn)鏡或者小型天文望遠(yuǎn)鏡,但好在可以以月亮為參照尋找金星。就我國(guó)來(lái)說(shuō),掩食帶以外的中高緯度地區(qū)會(huì)看到“金牙”與“月牙”擦肩而過(guò)的畫(huà)面。白天看星星,你想不想挑戰(zhàn)一下?(記者周潤(rùn)健,海報(bào)制作:馮娟)
