Lyridy
Lyridy jsou meteorický roj pojmenovaný podle souhvězdí Lyry, ze kterého zdánlivě vylétá a kde se nalézá jejich radiant. Země kříží během své oběžné dráhy kolem Slunce jejich roj každoročně od 19. do 25. dubna. Maximum připadá na 22. dubna. Zdrojem meteorického roje je dlouhoperiodická kometa C/1861 G1 (Thatcher). Lyridy jsou známy již 2 600 let.

Lyrid meteor shower radiant point.jpeg

The radiant point of the Lyrid meteor shower is near the star Alpha Lyrae (proper name Vega), the brightest star in the constellation Lyra the Harp. At the time of the Lyrids' peak each year (around April 22), you will find this radiant point in the northeast in late evening and higher in the sky as night passes. Although the meteors appear to radiate from a point in the sky near the bright star Vega, they are not truly associated with this distant star. Instead, meteors in annual showers like the Lyrids originate as relatively nearby bits of debris left behind in the orbits of comets. The comet associated with the Lyrids is periodic Comet C/1861 G1 Thatcher.
