The largest verified impact crater on Earth, Vredefort Crater in South Africa. Measuring a staggering 250 – 300 km (155 – 186 miles) across, this crater was formed over 2 billion years ago by an asteroid estimated 10 km (6 miles) in size.
Google Sightseeing is a great blog which in its own words states ‘ why bother seeing the world for real’ when you can use Google Earth! Well I guess it helps reduce the impact to the environment as a consequence of flying to these locations.
Anyway this blog posting has a great range of impact craters to explore
A meteor is in the sky , a meteorite has already landed on the the surface, an asteroid is bigger than 1km in diameter. A shooting star is essentially a a meteor breaking up in the atmosphere.
This interesting website from the ever excellent Boston Globe has a great range of technologies that we humans could employ to divert a potentially catastrophic meteor impact event.
