Why is a solar eclipse so short?
A solar eclipse occurs when the moon passes between Earth and the sun, blocking the sun’s light and forming a fast-moving shadow on the surface of our planet. Because of the geometry of eclipses, the moon’s shadow is narrow when it reaches Earth, so the region from which the eclipse is visible is small.Click to…

Furthermore, why does a solar eclipse last for only a few minutes?Because the Moon is much smaller than the Earth, its shadow can only cover a small part of the Earth’s surface, such that solar eclipses can only be seen from certain locations on the Earth. A total solar eclipse only lasts for a few minutes, as the Moon’s shadow moves east at over 1700 km/h.One may also ask, what position is a solar eclipse possible? An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon’s shadow happens to fall upon Earth’s surface at that time, we see some portion of the Sun’s disk covered or ‘eclipsed’ by the Moon. Hereof, how long do solar eclipses last? During the brief period of totality, when the sun is completely covered, the beautiful corona — the tenuous outer atmosphere of the sun — is revealed. Totality may last as long as 7 minutes 31 seconds, though most total eclipses are usually much shorter.Is solar or lunar eclipse longer?The Sun and Moon both have an apparent angular diameter of about half of a degree. The Moon moves at a rate of about half of a degree an hour. So we can see that from beginning to end, a solar eclipse will be less than two hours, while a lunar eclipse can be considerably longer.
