NASA: The Only Thing Stopping a City-Destroying Asteroid Is Blind Luck

NASA: The Only Thing Stopping a City-Destroying Asteroid Is Blind Luck

So you know how we all kind of thought that our odds of getting destroyed by an asteroid were remarkably low? Yeah, that was wrong . According to new research, the odds of a large-scale asteroid impact are actually three to ten times higher than we thought. And the only thing stopping total and utter destruction? Sheer, dumb luck.

This beautiful tracking video shows Asteroid 2013 XY8 buzzing our planet on Tuesday night. It’s estimated to be up to 230 feet across, more than three times the size of the Chelyabinsk asteroid that caused havoc earlier this year. And we only discovered it four days ago. This could’ve gotten hairy.

Physicists Claim It Would Be Impossible to Nuke an Earth-Killing Asteroid [Science]

If you’ve always assumed that the idea proposed in Armageddon could save us in the face of a crisis, by destroying an asteroid to avert the destruction of Earth, think again. Physicists from Leicester University, UK, have calculated that such a feat would require a bomb a billion times stronger than the biggest bomb ever detonated on Earth. More »

Just when you’re numbing to robot, zombie and nuclear apocalypse scenarios, some old-fashioned asteroid paranoia pops up to surprise you. The B612 Foundation, which gets funding from, well, anyone, has just announced plans to launch Sentinel, a space telescope which will wander the vacuum cataloging asteroids in our inner solar system. Their goal is to track asteroid orbits and predict large impacts up to 100 years in advance, giving us plenty of time to find a solution (or enjoy our final days). Construction doesn’t start til late fall, with the launch expected in around five years, so it won’t be any use in disproving the 2012 doomsday believers out there. You can find out more about the project and donate to the foundation at the source link, or jump past the break for a video explanation, Aerosmith not included.
