Large asteroid 'under close watch'

A 250-foot asteroid named Apophis is set to pas within 20,000 miles of the Earth in 2029. (MSNBC) That's a pretty big rock (the asteroid suspected in the legendary Tunguska event was just 100 feet across) and very close (the asteroid that grabbed headlines earlier this year was 50,000 miles out… the moon is 230,000 miles away).

Apophis probably won't wipe out any species (the rock that scientists believe contributed to the downfall of the dinosaurs was probably 6.2 miles across). NASA is tracking 6,000 near-Earth objects. Apophis is one of 1,000 "potentially hazardous bodies." There are 773 larger than one kilometer in diameter.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
