It's about 14 meters wide, 3 meters deep. On May 2, 2006, a meteoroid hit the Moon's Sea of Clouds (Mare Nubium) = with 17 billion joules of kinetic energy=97about the same as 4 tons of = TNT," ... impact fireball was video-recorded using a 10-inch telescope. ... "stuff hits the Moon all the time," but this is the best-ever = recording of an explosion in progress: "The duration of the fireball was only four-tenths of a second," Taking into account the duration of the flash and its brightness (7th = magnitude), Cooke was able to estimate the energy of impact, the = dimensions of the crater, and the size and speed of the meteoroid. "It = was a space rock about 10 inches (25 cm) wide travelling 85,000 mph = (38 km/s)," he says. If a rock like that hit Earth, it would never reach the ground. "A 10-inch meteoroid would disintegrate in mid-air, making a = spectacular fireball in the sky but no crater." -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
