A Mysterious 'Doomsday' Asteroid is Set to Pass Close to Earth This Week. A potentially hazardous asteroid, estimated to be around 1,100 feet in diameter, is scheduled to make a close approach to Earth this week. The asteroid, named 2000 WO10, has been classified as a 'potentially hazardous' object due to its size and close proximity to our planet. While astronomers have downplayed the risk of an impact, the flyby has sparked concerns about the asteroid's potential trajectory and the need for continued monitoring. As the asteroid hurtles through space, scientists are keeping a close eye on its path to ensure the safety of our planet.
