1. Chicxulub Impact: This is arguably the most famous extraterrestrial impact on Earth, believed to have caused the extinction of the dinosaurs. Around 66 million years ago, a large asteroid or comet about 11 to 81 kilometers in diameter hit the Earth in what is now the Yucatan Peninsula in Mexico. The impact caused a crater about 180 kilometers in diameter and 20 kilometers in depth. The energy released from the impact caused massive fires, tsunamis, and a "nuclear winter" effect, leading to the extinction of non-avian dinosaurs.

2. Vredefort Impact: This is the largest verified impact crater on Earth, located in South Africa. It is estimated to be over 2 billion years old. The asteroid that caused this crater is believed to have been about 10-15 kilometers in diameter. The impact would have caused significant environmental changes, including fires, tsunamis, and a shift in the Earth's climate.

3. Tunguska Event: This event occurred in 1908 in Siberia, Russia. It is believed to have been caused by a meteoroid about 60-190 meters in size exploding in the Earth's atmosphere. The explosion flattened about 2,000 square kilometers of forest but left no crater. The Tunguska event is the largest impact event on Earth in recorded history.
