Impact Events & Near Misses in History
On this page we list some of the prominent impact events from history which may be of interest to this project. The data is under construction.
- Shoemaker-Levy 9 (July 1994), impact site planet Jupiter, 21 pieces of comet, impact velocity 60 km/s, energy 6,000 Gtons TNT equivalent.
- Tunguska (1908), Siberia, comet air detonation 5-10 km above ground, energy 10 - 15 Mtons TNT equivalent.
- Burckle Crater (2,800 - 3,000 B.C), Indian Ocean, comet impact, 30 km wide crater.
- Meteor Crater, (50,000 years ago), Arizona, 50 m Nickel-Iron asteroid, impact velocity 2.8 - 20 km/s, energy 10.7 - 26.2 Mtons TNT equivalent.
- K-T event (66 million years ago), asteroid or comet 10-15 km diameter, impact velocity 20 km/s, energy 30,000 - 100,000 Gtons TNT equivalent.
- Asteroid 2018 GE3 (April 2018), passed within 119,500 miles away, 150 - 360 ft in diameter object, spotted only 21 hours prior to closest approach.
- 'Omuamua (Oct 2017), suggested impact energy 4.2 - 46.9 Gtons TNT equivalent.
