0 An eclipse happens when the Sun, the Earth and the Moon stand in one straight line, so that one of them casts its shadow on another. 1 In a solar eclipse the Moon passes between the Sun and the Earth and its shadow falls on the Earth: for a few minutes the Sun is hidden and day turns almost into night, but only along a narrow strip of the Earth. 2 In a lunar eclipse the Earth passes between the Sun and the Moon and the Earth's shadow falls on the Moon: the Moon goes dim and often turns coppery red, and everyone on the night side of the Earth can see it. 3 The Moon is about 400 times smaller across than the Sun but also about 400 times closer, so in our sky they look almost the same size, which is why the Moon can just cover the Sun, like a coin held near your eye covering a far-away house. 4 There is no eclipse every month because the Moon's path is tilted a little, so usually it passes just above or below the line between the Sun and the Earth. 5 An eclipse happens when the Sun, the Earth and the Moon are in a straight line. 6 In a solar eclipse the Moon is between the Sun and the Earth. 7 In a lunar eclipse the Earth is between the Sun and the Moon. 8 A solar eclipse can happen only at new moon. 9 A lunar eclipse can happen only at full moon. 10 A total solar eclipse is seen only along a narrow strip of the Earth and lasts only a few minutes in each place. 11 A lunar eclipse can be seen from the whole night side of the Earth and can last more than an hour. 12 During a total lunar eclipse the Moon often looks red, because a little sunlight is bent through the Earth's air onto it. 13 The Sun is about 400 times wider than the Moon and about 400 times farther away, so they look almost the same size in the sky. 14 Eclipses do not happen every month because the Moon's path around the Earth is slightly tilted. 15 You must never look at a solar eclipse without special eclipse glasses. 16 Looking at a lunar eclipse is safe, because it is only the Moon. ← previous The shape and size of the Earth, the poles and the equatornext → Time zones and the calendar↑ back to World This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/world/8-eclipses/
