Top 10 most impressive asteroid tracks in the world

Experts estimate that around 200 asteroids ranging in size from 10 cm to 10 meters collide with the earth every year. 1 or 2 larger asteroids, about 50 meters, strike our planet every year as well. For the strongest, exceeding 1000 meters, the phenomenon occurs approximately every 1000 years. Specialists who also claim that every 300,000 years, an asteroid one km in diameter collides with the earth. So suddenly, we find all around the world a certain number of rather spectacular impacts. The traces of very sturdy asteroids, which have not completely decomposed in the atmosphere and which, in their time, have caused a lot of damage.

1. The Manicouagan Astrobleme (Canada)

Largest impact crater in the world, this astrobleme is also one of the oldest (213 to 215 million years). Covering 1942 km2 of surface, it was created by the fall of an asteroid 5 km in diameter. And no, he was not the one who caused the extinction of the dinosaurs.

2. The Pingualuit crater (Canada)

Paradoxically, this crater is the smallest of all the craters due to the fall of an asteroid in all the territory of Canada. Small but spectacular! Trace of an event that occurred 1.3 million years ago, it now houses a lake.

3. Meteor Crater (USA)

A stunning crater near Flagstaff, Arizona. With a diameter of about 1300 meters and a depth of 190 meters, it was formed 50,000 years ago following the fall of an asteroid 50 meters in diameter. We can now visit it but for that, you have to pay! It is also here that NASA astronauts came to train in the 1960s before going for a walk on the moon.

4. Wolf Creek (Australia)

Made popular thanks to the film of the same name, the Wolf Creek crater measures 875 meters in diameter and is 60 meters deep. Relatively verdant, it was discovered in 1947 and was formed 300,000 years ago. And if in the film, it is the hunting ground of a completely crazy redneck, the only risks that visitors can actually run are more related to the unstable nature of the terrain.

5. Kids Bluff (Australia)

We stay in Australia with this superb mountainous crater, located 160 miles from Alice Springs. A 142.5 million year old gentleman, sacred to the Aborigines, with a diameter of 5 km.

6. Kaali Crater (Estonia)

A rather original site, grouping together 9 impact craters, in the woods, in the shade. Relatively recent (about 4000 years), these craters are filled with water and therefore stand out as a kind of natural pools. The largest of the lot measures 110 meters in diameter.

7. Roter Kamm (Namibia)

Experts have a hard time assessing the period during which this African crater was formed. As a result, they claim that the impact must have occurred 0.3 or 3.7 million years ago. A beautiful crater 2.5 km in diameter and 130 meters deep. It is now filled with sand but nevertheless still stands out quite well.

8. Vredefort Dome (South Africa)

Here it is ! The largest impact crater in the world! 2.023 billion years old, it is home to the town of Vredefort and is listed by UNESCO. The asteroid that formed it was between 10 and 15 km in diameter. The crater measures 300 km.

9. Upheaval Dome (USA)

Here is one that hides its game well. So much so that for a long time, geologists thought it was a volcanic structure. So no, not at all. The Dome of Upheaval was indeed born following the impact of an asteroid. It is located in Canyonlands National Park in Utah.

10. Middlesboro (USA)

At one time, in the United States, it was Armageddon and Deep Impact every four mornings! In fact, there are so many craters in Uncle Sam’s that sometimes, to save space, we actually built things in them. Like the town of Middlesboro, Kentucky. A crater city therefore, 5 km in diameter.

Even better than at the cinema!Source: Wikipedia
