Question

How often do solar eclipses occur? a) approx. once a year b) approx. twice a year

Answer 1

Answer:-

Solar eclipses, partially or totally occur an approximately 2 times (twice) a year.

Total eclipses occur an average 18 months, but are only visible on less than half a percentage of the earth surfaces.

Any particular point on the earth experiences one eclipses an average of more than 350 years. Total eclipses require the moon to be in close orbit to the earth or perigee in order to fully cover the sun. If the moon is farther away at apogee, than the moon cannot totally block the sun .Because the moon varies its distance to the earth width of the shadow cast in an eclipses varies with every eclipses.

There would be more frequent eclipses, except the moon’s orbit is off about five degree in relationshio.to the earth orbit around the sun. This result in the moon typically passing a little bit above or below the sun .The moon is getting farther from the earth at a rate of 1.48 inches per year, hundreds of millions of years from now the moon will no longer be able to totally cover the sun.

Severe eye damage can occur if observers look directly at an eclipses with the naked eye, telescope or anything not approved for eclipses viewing scientists used special filters and equipment’s to view eclipses.
