By Bill Nye | Published: February 15, 2013 – 4:00 pm My O my, wow… the 7,000-ton meteor over the Chelyabinsk region slammed into our atmosphere at 15,000 km per hour (33,000 miles an hour). Witnesses could see the flash of light 500 kilometers away. It was probably 15-meters (50 feet) across. When these things hit the atmosphere they just blow up. It’s not combustion, at least at first; it’s a rock slamming into something air so hard, that it disintegrates.
