The mission, named DART — Double Asteroid Redirection Test, hit Dimorphos, an asteroid that orbits a bigger asteroid called Didymos. Neither asteroid is a threat to Earth. Neither asteroid is a And it's moving fast (relative to Earth), clipping through space at about 15.3 miles (24.6 kilometers) per second. NASA initially reported there was a 1 in 560 chance that 2023 DW could impact 0:00. 1:27. A newly discovered asteroid more than 200 feet wide will zoom in between Earth and the moon Saturday afternoon in an occurrence NASA says happens only once a decade. The asteroid, 2023 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 Now, NASA has revised this estimate, putting the asteroid's chances of hitting Earth at around 1-in-770, meaning it has a 99.87% chance of missing us. The European Space Agency's (ESA) Near-Earth . Bennu is categorized as a near-Earth asteroid, and scientists say there is a 1-in-1,750 chance it could slam into Earth during a series of very close passes between 2175 and 2199. Bennu is not Around 66 million years ago, an asteroid measuring at least 6 miles (10 kilometers) across dealt the dinosaurs' world a devastating blow, triggering earthquakes, tsunamis, volcanic eruptions and Apophis is a near-Earth asteroid, meaning its orbit around the Sun brings it within 1.3 times the distance between the Sun and Earth. Its full name is Apophis 99942. After Apophis was discovered in 2004, the asteroid was given a 2.7% chance of hitting Earth in 2029, causing a great deal of media attention. It also for a time had a small chance And a provocative new study suggests they are bigger than previously thought—meaning Earth is more at risk of getting hit hard, says James Garvin, chief scientist of NASA’s Goddard Space Flight Center, who presented the work last week at the Lunar and Planetary Science Conference. “It would be in the range of serious crap happening.”. The most likely date of impact, where the orbits are predicted to be closest, is September 24, 2182. On this date, there is a one in 2,700 chance of impact according to NASA, or around 0.037
