The Perséid meteors from 2018


Meteors (or shooting stars) are small pieces of dust generally left by the passage of a comet which gradually disintegrates with each passage close to the Sun. The Earth in its movement along its orbit crosses the same piles of debris on the same date each year.

During the month of August, the Earth encounters the debris left by comet Swift-Tuttle which creates this shower of shooting stars that seem to come from the constellation of Perseus, hence the name Perseids.

The photo below is a composite of several photos taken during the night of August 13, 2018 showing that the meteors seem to come from the same region of the sky when in reality it is the Earth that is hurtling in this cluster of dust
