The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet's surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.17 Oct 2021

How big was the space rock that killed the dinosaurs?
Dino-killing asteroid: How big was it? The dimensions of Chicxulub Crater — about 90 miles wide by 12 miles (20 km) deep — give us a rough idea of the impactor's size. For example, Siraj and Loeb calculated that the incoming object was likely about 4.3 miles (7 km) wide.
What is the biggest crater on Earth?
the Vredefort Crater Some of the largest impacts ever to occur on Earth are barely visible to us today (at least not in the traditional 'hole in the ground' sense.) In South Africa, the Vredefort Crater, also known as the Vredefort Dome is the world's largest known impact crater, according to NASA Earth Observatory.
How big was the crater that hit Earth?
According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago. This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.
How big is the Apophis asteroid?
185 m 99942 Apophis/Radius
How big of an asteroid would it take to destroy the earth?
Ultimately, scientists estimate that an asteroid would have to be about 96 km (60 miles) wide to completely and utterly wipe out life on our planet.
Can you visit Chicxulub crater?
You can visit the Museum of Science of the Chicxulub Crater in Merida, Mexico, to learn more about this crater. Scientists believe that the comet that created this crater is also responsible for creating the beautiful blue water sinkholes that dot the area around Merida.
How big was the meteorite that hit Sudbury?
10 to 16 kilometres A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario (700 kilometres away)! An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet (Figure 2).
