Skyscraper-Sized Asteroid to Zoom Past Earth This Weekend

A skyscraper-sized asteroid will pass within three-quarters the average distance between Earth and the moon on Saturday, June 29. The asteroid, named 2024 MK, is estimated to be about 480 feet (146 meters) across and will be traveling at roughly 21,000 mph (34,000 km/h) during its closest approach. Although it poses no threat to Earth, NASA classifies it as a ‘potentially hazardous asteroid’ due to its size and orbit. The asteroid will zoom back out toward the asteroid belt and will not return until 2037.

Earth’s Day: A Constantly Evolving Rotation

Earth’s day, while seemingly constant at 24 hours, has actually fluctuated throughout history, from a shorter 19-hour day a billion years ago to a potential 25-hour day in the future. This ongoing change is driven by various factors, including the moon’s gravitational pull, Earth’s internal processes, and even human activities.
