Question

why meteor showers are not as common today ,than was in past?
​

Answer 1

Explanation:

Meteor showers occur when the earth in its orbit around the Sun passes through debris left over from the disintegration of comets. Although the earth's orbit around the Sun is almost circular, most comets travel in orbits that are highly elongated ellipses. As a result, some comets have orbits that intersect or partially overlap the earth's path.
