An enormous asteroid—big enough to leave a six-mile-wide crater and darken the world with dust if it hit Earth—will harmlessly zip by our planet on April 29. A one-mile-wide asteroid on a collision course with Earth would hit the planet at around 30,000 miles per hour. An asteroid of this magnitude has roughly the same amount of energy as a one-million "As of now, no known asteroid larger than 140 meters in size has a significant chance to hit Earth for the next century. However, less than half of the estimated 25,000 NEOs that are 140 meters The short answer is no, asteroid Apophis will not hit the Earth, and it's important to get that out of the way early. Near-Earth Objects (NEOs) are high-priority research for government agencies An asteroid hurtling towards the Earth's atmosphere has just recently been discovered by NASA. Asteroid 2023 BU was spotted by NASA 's Centre for Near Earth Object Studies (CNEOS) on Saturday (21 There’s more than a 99.9 percent chance that Bennu will not hit Earth in the next three centuries, and an impact from Bennu wouldn’t cause a mass extinction like the dino-killing Chicxulub impact 66 million years ago. That asteroid was probably about six miles across; Bennu is less than a third of a mile wide, on average. You may want to clear your calendar because scientists think an asteroid may hit Earth. NASA scientists are keeping a close eye on asteroid Bennu, a 1,610-foot-wide cosmic object that could smash CNN — A newly discovered asteroid roughly the size of an Olympic swimming pool has a “small chance” of colliding with Earth in 23 years, with a potential impact on Valentine’s Day in 2046, .
