The Eta Aquarids: A spring meteor shower from Comet Halley

The meteors do not actually originate near Aquarius; the placement of the radiant there is an orbital coincidence and merely guides skywatchers to the correct point in the sky. The meteors are a stream of litter left behind by Comet Halley, which is the most famous periodic comet, coming around every 76 years. date back to at least 273 B.C., according to NASA's Jet Propulsion Laboratory. It also arrived in 43 B.C., one year after Julius Caesar was assassinated in Rome.

The comet was first pegged as a periodic one — a comet that visits the inner solar system again and again — in 1705. Astronomer's calculations showed that three comets sighted in 1531, 1607 and 1682 followed very similar trajectories. He predicted the comet would come again in 1759. Halley did not live to see the comet's reappearance, but it came on schedule as he had predicted.

The last time Comet Halley passed by Earth was in 1986, which means it should enter our view again in 2061.
