The April Lyrids are a meteor shower lasting from April 16 to April 26 each year.[4] The radiant of the meteor shower is located in the constellation Lyra, near its brightest star, Vega. The peak of the shower is typically around April 22 each year.

The source of the meteor shower is particles of dust shed by the long-period Comet C/1861 G1 Thatcher.[1] The April Lyrids are the strongest annual shower of meteors from debris of a long-period comet, mainly because as far as other intermediate long-period comets go (20010,000 years), this one has a relatively short orbital period of about 415 years. The Lyrids have been observed and reported since 687 BC; no other modern shower has been recorded as far back in time.[5]  ...
