![]() ![]() ![]() The current biggest known threat is an asteroid called (410777) 2009 FD, which has less than a 0.2% chance of hitting Earth in 2185, according to NASA. In March, an asteroid similar in size to the Golden Gate Bridge whipped past our planet - the largest and fastest asteroid to pass by Earth in 2021. 1, the asteroid will come within about 1.43 million miles (2. But, scientists believe some would survive. Instead of circling the sun every 359 days, it will move into an oval orbit lasting 425 days, according to NASA. Scientists believe past stray asteroids colliding with Earth played a major role in the planet's evolution. NASA scientists say it would take an asteroid 60 miles (96 kilometers) wide to totally wipe out life on Earth. The asteroids path will be drastically altered by Earths gravity once it zips by. Also known as asteroid 99942, the near-Earth object is estimated to be about 1,100 feet (340 meters) across and could cause serious damage to the planet's surface if it were to hit. Despite the enormous destructive potential, the. This explosion released an energy equivalent to nearly 30 atomic bombs. It generated a fireball and exploded more than 20 km above the Russian city of Chelyabinsk. Most asteroids orbit the sun between Mars and Jupiter, but occasionally, their orbital paths are influenced by other planets' gravitational pulls, altering their paths. Chelyabinsk In 2013, a rocky-type asteroid about 20 meters in diameter and a mass of over 10,000 tons hit Earth’s atmosphere. "I expect there will be new asteroids added to this list during the week," he said. Thursday and Saturday bring even more asteroids.Ĭhodas told CBS News that it is "normal" to have this many asteroids pass by. They will come within about 1.9 million miles and 3.6 million miles of Earth, respectively. Meanwhile, 63-foot 2021 JW6 will pass on Wednesday, along with 2021 KE1, which is about 53 feet. They came within 181,000 miles and 694,000 miles of Earth, respectively. It's difficult to imagine 1 million megatons, so let's try some smaller sizes. NASA’s OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agency’s existing models of its trajectory. Or at least put the possibility into the same category as. An asteroid that big traveling at that speed has the energy roughly equal to a 1 million-megaton bomb. comes to the faint possibility that an asteroid will strike Earth with catastrophic consequences. Asteroid 2021 KT2, which is about 23 feet, also passed on Tuesday, as did 2018 LB, which is about 70 feet. If a mile-wide asteroid hit Earth, it would strike the planet's surface at about 30,000 miles per hour (48,280 kilometers per hour). ![]()
