Leónidas

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.

O fenómeno das Leónidas (português europeu) ou Leônidas (português brasileiro) consiste numa chuva de meteoros associada à passagem do cometa Tempel-Tuttle. Pode ser observada todos os anos por volta de 17 de Novembro, altura em que a Terra se cruza com o rasto de pequenas partículas sólidas, conhecidas como meteoróides, ejectadas pelo cometa quando se aproxima do Sol. As Leónidas foram assim baptizadas devido ao facto de o seu radiante se localizar na constelação de Leo e são famosas pela espectacularidade do fenómeno. A recorrência de chuvas particularmente prolíficas tende a ser de 33 em 33 anos, associada à órbita de 33 anos do Tempel-Tuttle, podendo originar nessas alturas verdadeiras tempestades de estrelas cadentes, que chegam a atingir os milhares de meteoros por hora; com efeito, algumas datas assinaláveis para este fenómeno foram 1799, 1833, 1866, 1966 e 1998. No entanto, tempestades desta magnitude são difíceis de prever, pois duram apenas algumas horas e podem ser observáveis apenas a partir de locais remotos.
