NASA has issued a warning about a massive 'Christmas Eve asteroid' the size of a 10-story building that will pass by Earth at 14,743mph on December 24. The asteroid, named 2024 XN1, will come within 4.48 million miles of Earth, posing no threat of collision. Despite its size, the asteroid will not be visible to amateur astronomers due to its distance. This close approach serves as a reminder of the potential dangers posed by near-Earth objects, with experts emphasizing the devastating impact such an asteroid could have if it were to collide with our planet.
