Astronomy enthusiasts across China will be blessed to see on a spectacular transit of Venus on the morning of June 6, the last such astronomical phenomenon in the century, Yangcheng Evening News reported.

A transit occurs when a planet passes directly between the sun and the Earth; therefore the planet, in this case Venus, becomes visible and hence obscures a small portion of the solar disk.

The next transit of Venus will take place on Dec. 11, 2117.

據(jù)《羊城晚報(bào)》報(bào)道，天文愛好者可以在6月6日上午一飽眼福，觀測(cè)到本世紀(jì)最后一次金星凌日。

凌日是指行星（本次是金星）運(yùn)行至太陽和地球之間，因此可以觀測(cè)到太陽圓盤上有一個(gè)小黑點(diǎn)。

下一次金星凌日將發(fā)生在2117年12月11日。
