O cometa Swift-Tuttle possui ressonância orbital com Júpiter, na proporção de 1:11 (uma volta de Júpiter para 11 voltas do cometa). O seu núcleo sólido mede cerca de 27km. Como efeito de comparação, o asteróide que supostamente teria matado os dinossauros possuiria 10km de núcleo sólido.
Considerado uma ameça ao nosso planeta, existe uma possibilidade do Swift-Tuttle colidir com a Terra em 2126. A conclusão foi graças à redescoberta da órbita do cometa em 1992, onde observou-se que o periélio estava atrasado em 17 dias. Caso o periélio esteja atrasado em 15 dias no ano de 2126, é provável que sua rota entre em conflito com a órbita do planeta.
O pico da proximidade da Terra com a órbita do cometa são os meses de julho e agosto, onde é possível ver o Perseidas com binóculos simples ou mesmo a olho nu no hemisfério norte, principalmente em pontos rurais, de céu claro. O fenômeno consiste em uma chuva de meteoros associada ao Swift-Tuttle.
Comet Swift-Tuttle has orbital resonance with Jupiter, at a ratio of 1:11 (one lap to 11 laps Jupiter comet). Its solid core measures about 27km. As a comparison, the asteroid that killed the dinosaurs supposedly possess 10km solid core.
Considered a threat to our planet, there is a possibility of the Swift-Tuttle collide with Earth in 2126. The conclusion was rediscovered thanks to the orbit of the comet in 1992, where it was observed that the perihelion was delayed by 17 days. If the perihelion is delayed by 15 days in the year 2126, it is likely that your route conflicts with the planet's orbit.
The peak of the proximity of the Earth to orbit the comet are the months of July and August, where you can see the Perseids with simple binoculars or even the naked eye in the Northern Hemisphere, especially in rural spots, clear sky. The phenomenon consists of a meteor shower associated with the Swift-Tuttle.
