What causes a solar eclipse and why are they so rare.

A solar eclipse occurs when the moon passes completely in front of the sun and creates a shadow that darkens a portion of the earth. In a solar eclipse the moon passes between earth and the sun and stops some or all of the sun s light from reaching earth. A solar eclipse occurs when a portion of the earth is engulfed in a shadow cast by the moon which fully or partially blocks sunlight. 21 will attract a huge audience and rightly so.

In a total solar eclipse the moon completely covers the sun. But any given spot on our planet s surface gets darkened by the moon s shadow on average only once about every 400 years so in that sense totality is indeed rare cosmic coincidence. They occur roughly once every year or two somewhere on earth. They won t show up just because solar eclipses are extremely beautiful.

21 2017 is an exceedingly rare event. So solar eclipses could happen once a month. Here s why a total solar eclipse occurs on a given spot on the planet only once every 375 years. This occurs when the sun moon and earth are aligned.

There are three kinds of solar eclipses. In a partial solar eclipse the sun is partly covered when the moon passes in front of it. Such alignment coincides with a new moon indicating the moon is closest to the ecliptic plane in a total eclipse the disk of the sun is fully obscured by the moon. Looked at another way total solar eclipses aren t rare.

They occur when the same eclipse changes from an annular to a total solar eclipse and or vice versa along the eclipse s path.
