The Perseids are a prolific meteor shower associated with the comet Swift–Tuttle that are usually visible from mid-July to late-August.The meteors are called the Perseids because they appear from the general direction of the constellation Perseus and in more modern times have a radiant bordering on Cassiopeia and Camelopardalis.
[5] [10]: 10–13 [6] Fossil evidence for an instantaneous extinction of diverse animals was found in a soil layer only 10 centimeters (3.9 in) thick in New Jersey, 2,500 kilometers (1,600 mi) away from the impact site, indicating that death and burial under debris occurred suddenly and quickly over wide distances on nearby land.

A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost ...
Meteorites might look like boring bits of rock – but each one has a fascinating story.
The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
Its diameter was approximately 23-36 miles (37-58 km), Drabon said, making it about 50-200 times the mass of the asteroid that wiped out the dinosaurs, aside from their bird descendants.
The Taurids are an annual meteor shower, associated with the comet Encke.The Taurids are actually two separate showers, with a Southern and a Northern component. The Southern Taurids originated from Comet Encke, while the Northern Taurids originated from the asteroid 2004 TG 10, possibly a large fragment of Encke due to its similar orbital parameters.
The Leonids are famous because their meteor showers, or storms, can be among the most spectacular. Because of the storm of 1833 and the developments in scientific thought of the time (see for example the identification of Halley's Comet), the Leonids have had a major effect on the scientific study of meteors, which had previously been thought to be atmospheric phenomena.
