Six years ago today, a small asteroid with an estimated size of 65 feet (20 meters) entered Earth’s atmosphere. The February 15, 2013, asteroid was moving at 12 miles per second (~19 km/sec) when it struck the protective blanket of air around our planet, which did its job and caused the asteroid to explode.

Why do meteors burn up in the atmosphere?
When the meteor hits the atmosphere, the air in front of it compresses incredibly quickly. When a gas is compressed, its temperature rises. This causes the meteor to heat up so much that it glows. The air burns the meteor until there is nothing left.

How big was the meteor that killed all the dinosaurs?
Known as the Chicxulub impactor, this large object has an estimated width of 6 miles (9.6 kilometers) and produced a crater in Mexico’s Yucatan peninsula that spans 90 miles (145 kilometers).
Where do I look to see the Leonid meteor shower?
Where to see them. The radiant, or point of origin, of the Leonid meteors is located in the constellation of Leo, the lion. The Leonid meteor shower gets its name from the constellation Leo, the lion, where its meteors appear to originate. But you can look in just about any direction to enjoy the show, Cooke said.
How many meteors hit the Earth every day?
Every year, the Earth is hit by about 6100 meteors large enough to reach the ground, or about 17 every day, research has revealed. The vast majority fall unnoticed, in uninhabited areas. But several times a year, a few land in places that catch more attention.
What is happening when we see a meteor shower?
Meteor showers occur when dust or particles from asteroids or comets enter Earth’s atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
Did any dinosaurs survive?
Part of the Dinosaurs: Ancient Fossils, New Discoveries exhibition. Not all dinosaurs died out 65 million years ago. Avian dinosaurs–in other words, birds–survived and flourished.
Did any dinosaurs survive the meteor?
The geologic break between the two is called the K-Pg boundary, and beaked birds were the only dinosaurs to survive the disaster. The happenstances of evolution had given birds a lucky break, the key events set in motion long before the asteroid struck.
How long did dinosaurs live after meteor?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
What is the best time to see the Leonid meteor shower?
The meteors are created by debris from the comet 55P/Tempel-Tuttle which takes 33 years to orbit the sun once. The Leonids are best viewed starting at about midnight local time. To catch a glimpse, find an area well away from light pollution from city or streetlights.
