Perseidn.

Perseid (n.)meteor from an annual shower that appears to radiate from the constellation Perseus, 1867, from Modern Latin Perseides (plural), from Greek Perseis "daughter of Perseus" (see Perseus; also see -id). The name might have been introduced in English via the writings of Italian astronomer Giovanni Schiaparelli. Other recorded old names for them in English include August meteors and Tears of St. Lawrence.
