しし座流星群

The Leonids ( ) are a prolific annual meteor shower associated with the comet Tempel–Tuttle, and are also known for their spectacular meteor storms that occur about every 33 years. The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from that point in the sky. The name is derived from Greek and Latin with the prefix Leo- referring to the constellation and the suffix -ids signifying that the meteor shower is the offspring of, descendant of, the constellation Leo.

AI overview

The Leonids are a meteor shower that occurs every year and is produced by dust particles from the comet Tempel–Tuttle, with the additional distinction of creating especially dramatic "meteor storms" roughly every 33 years. The shower gets its name because the meteors appear to come from the direction of the constellation Leo in the night sky.
