Fastest meteor shower

The fastest annual meteor shower is the Leonids, which occur between 15 and 20 November each year. They enter Earth's atmosphere at around 71 kilometres (44 miles) per second, and begin to glow at an altitude of around 155 km (96 miles). The high speed of the Leonids is because the motion of the parent meteoroid stream, from comet 55P/Tempel–Tuttle, is almost directly opposite to the orbital motion of Earth around the Sun. This results in an almost head-on collision between the tiny particles and the Earth.

The Leonids reach their maximum intensity on 18 November each year
