Earth encounters this material twice a year, resulting in the Eta Aquariid meteor shower in May and the Orionids in October. Halley's Comet itself is not expected to be visible from Earth again until 2061.
One of the best-known meteor showers peaks this week and will remain active until 7 November, bringing debris left behind by Halley's Comet to the night sky.
The meteors appear to radiate from the constellation of Orion, which is where the shower gets its name, though they can appear anywhere across the night sky. According to the details, the Orionids are particularly fast and can leave trails in the sky that last a few seconds after the meteor itself has gone.
Viewers will not need binoculars or a telescope, as the meteor shower is best viewed with the naked eye.
