【英語】ミチタン推測 練習問題16 [レベル4]ミチタン推測 英語
A total eclipse happens when the moon passes between the Earth and the sun and completely blots out the sun’s light, except for the corona of its outer atmosphere.
From Earth, the moon will appear to be the same size as the sun. This is possible because while the moon is 400 times smaller than the sun in diameter, it is also 400 times closer to Earth than the sun. When the two line up exactly, the skies go dark.
