A big asteroid will buzz Earth today (March 25), and you can watch the flyby live online.
The near-Earth asteroid, known as 2023 DZ2, is thought to be 140 to 310 feet (40 to 95 meters) wide. At around 3:30 p.m. EDT (1930 GMT), it will zoom within 107,500 miles (173,000 kilometers) of our planet, according to astronomer Gianluca Masi, who runs the Virtual Telescope Project. That's less than half the distance between Earth and the moon.
