But, actually, where do they come from? This shower of meteors comes from the most famous periodic comet: Halley’s comet (1P/Halley) identified as such by the English astronomer and physicist Edmond Halley in 1705. Each time it makes an incursion into the solar system internally, approximately once every 76 years – its last appearance dates back to 1986 and the next is expected in 2061 – it drops ice and rocky debris in its wake.
