How big was the Manicouagan asteroid?
5 kilometer
Scientists believe the crater was caused by the impact of a 5 kilometer (3 mile) diameter asteroid about 215.5 million years ago (Triassic Period).
Where is the Manicouagan crater located?
province of Québec
Manicouagan Crater, located in Canadian province of Québec, is one of the Earth’s oldest and the most visible impact craters. Manicouagan Crater was formed by an asteroid strike over 214 million years ago.
When did the Manicouagan crater hit Earth?
about 212 million years ago
The impact that formed Manicouagan is thought to have occurred about 212 million years ago, toward the end of the Triassic period. Some scientists believe that this impact may have been responsible for a mass extinction associated with the loss of roughly 60 percent of all species.
What meteor killed the dinosaurs?
Chicxulub
The impact that ended the age of dinosaurs some 66 million years ago was the worst single day that life on Earth has ever endured. A six-mile-wide asteroid called Chicxulub slammed into the waters off what is now Mexico, triggering a mass extinction that killed off more than 75 percent of Earth’s species.
How deep is the Manicouagan crater?
1,148′Manicouagan Reservoir / Max depth

What is the biggest meteor to hit Earth?
The Chelyabinsk meteor
The Chelyabinsk meteor was estimated to have caused over $30 million in damage. It is the largest recorded object to have encountered the Earth since the 1908 Tunguska event. The meteor is estimated to have an initial diameter of 17–20 metres and a mass of roughly 10,000 tonnes.
Where is the crater that destroyed the dinosaurs?
Yucatán Peninsula
‘ The impact site, known as the Chicxulub crater, is centred on the Yucatán Peninsula in Mexico. The asteroid is thought to have been between 10 and 15 kilometres wide, but the velocity of its collision caused the creation of a much larger crater, 150 kilometres in diameter – the second-largest crater on the planet.
What does this satellite image of Manicouagan crater show?
This false-color satellite image of Manicouagan Crater was captured by Sentinel-1A on March 21, 2015. The blue in the image shows the areas of ice and some water.
What is the rim-to-diameter measurement of the crater Manicouagan?
The rim-to-diameter measurement makes it the sixth-largest confirmed impact crater. The crater contains an annular lake (a circular lake caused by the impact of a meteor) called Manicouagan Reservoir which surrounds René-Levasseur Island.
What is the diameter of Manicouagan?
Manicouagan is one of the largest known terrestrial impact craters. It is 65 kilometers (40 miles) in diameter, but it is worth remembering that this is small compared with some of the larger lunar structures that measure more than 600 km (375 miles) across.
What is the Manicouagan impact?
The impact that formed Manicouagan is thought to have occurred about 212 million years ago, toward the end of the Triassic period. Some scientists believe that this impact may have been responsible for a mass extinction associated with the loss of roughly 60 percent of all species.
