Theasteroid is as wide as 21 buses parked end to end. A massive asteroid heading towards the Earth is set to pass by our planet at its closest point on Thursday. The asteroid known as “2023 FM” is between 120m and 270m in diameter — roughly equal to up to 21 buses lined up end to end — and it’s considered “potentially hazardous”. Anotherof Earth’s largest craters is the 180-km-wide Chicxulub crater, which is buried underneath Mexico’s Yucatán Peninsula.It was formed by the Chicxulub impact event approximately 66 million years ago, when Earth was struck by an asteroid or comet approximately 14 km (8.7 miles) in diameter.The impact event caused widespread Dateof Impact: 50,000 years ago. Crater Size: 4,000 ft. in diameter, 700 ft. deep. A popular tourist destination, the bowl-shaped Barringer Crater or “Meteor Crater” in Arizona is one of the Astorm of boulders “as deadly as Hiroshima” was accidentally unleashed by Nasa during tests to change the trajectory of an asteroid, scientists have found. Last September, the agency crashed TheChicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo. It was formed slightly over 66 million years ago when a large asteroid, about ten kilometers (six miles) in diameter, struck Earth.The crater is TheESA currently estimates that the asteroid has a 1 in 607 chance of impacting Earth. The soonest the asteroid would potentially impact Earth isn't for more than two decades. According to the European Space Agency, it's predicted that 2023 DW could impact the planet on Valentine's Day 2046. It also has the potential to impact on Newtheory explains possible origin of plummeting Chicxulub impactor that struck off Mexico. It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 Imagevia NASA/ JPL-Caltech.
