The space agency says the asteroid has the potential to hit Earth on February 14, 2046. NASA orbit analysts said they will continue to monitor the asteroid and update predictions as more data comes in. NASA discovered the asteroid, dubbed 2023 DW, on February 26. NASA officials give it a 1 in 560 chance of impacting Earth. "Often when new objects are first discovered, it takes several weeks of data to reduce the uncertainties and adequately predict their orbits years into the future," the agency said Tuesday.Īsteroid 2023 DW is currently at the top of NASA’s Earth impact monitoring list with a 1 out of 10 on the Torino scale, which means there is no cause for the public to worry. NASA's Planetary Defense Coordination Office said they have been tracking a new asteroid named 2023 DW that has a very small chance of impacting Earth on Feb. These objects are defined as asteroids that are more than about 460 feet (140 meters) in size with orbits that bring them as close as within 4.6 million miles (7.5 million kilometers) of Earth’s orbit around the Sun. When an NEO is discovered by a survey, additional telescopes are used to follow-up those discoveries (watch NASA Planetary Defense: Backyard Asteroid Observer) and add position measurements to the Minor Planet Center, which the Center for Near-Earth Object Studies (CNEOS) uses to compute a precise orbit and predict the NEO’s trajectory well in. ![]()
