Mother Nature provided a surprise light show over Russia early on February 14. That’s when a major meteor entered Earth’s atmosphere. The object was originally 17 meters (55 feet) in diameter. That’s as wide as a 5-story building is high. It had also weighed a whopping 10,000 metric tons, according to the National Aeronautics and Space Administration NASA).
The meteor was traveling about 65,000 kilometers (40,000 miles) per hour. It created a brilliant streak as it traveled across the sky for nearly 33 seconds. The meteor then exploded about 20 to 25 kilometers (12 to 15 miles) above Earth’s surface.
