Two asteroids to pass close to Earth on Wednesday
Two small asteroids in unrelated orbits will pass within the moon's distance of the Earth on Wednesday, according to NASA.
It's an unusual event that shows the need for closer monitoring of near space for Earth-threatening encounters, a scientist with the program said. The objects don't pose a threat to Earth, and they will not be visible to the naked eye, said Donald Yeomans, manager of NASA’s Near Earth Program, which tracks potentially hazardous asteroids and comets within 28 million miles of Earth. The objects will visible from Earth as tiny specks of light with the help of moderate-sized amateur telescopes, he said. http://news.blogs.cnn.com/2010/09/07...-on-wednesday/ Note:September 7th, 2010

yes, only a matter of time, lots of rocks out there.
The extinction of Dinosaurs was, according to one theory, caused by an asteroid strike which changed the earth's climate. and let's not forget the 1908 Tunguska impact when a 20 meter asteroid struck a siberian forest incinerating tress in a 9 mile radius and knocking them down in a 25 mile radius.

Redirecting them is easy and can be done with current technology. The easy way requires a some time before impact (like years) just send a spacecraft up and have it fly next to the asteroid. The gravitational field of the spacecraft tugs at the asteroid slowly pulling it off course. The harder way is to put a Mylar solar sail on the asteroid and have the solar wind push it out of the way. Downside is that it only works well close to the sun. The easy and quick way is to turn the asteroid in to a big unmanned Orion drive ship. Send up a bunch of nuclear bombs and detonate them one at a time every minute or so near the surface using the force of each explosion to push the asteroid. With sufficiently big bombs a decent sized rock could be redirected in the space of days or weeks. |

![]() Last Monday the Pleiades's looked very nice in my binoculars. ![]() But for hunting Asteroids well there ain't no stealth in space. This deals with combat but its applicable to searching for any hard to find target... Quote:
