Interplanetary collision called off

An asteroid heading for Mars is going to miss the angry red planet. Too bad, that would have been cool.

But there is a very cool graphic that results from the science surrounding this non event.

This is a moving GIF showing the evolution over time of the uncertainty region for the collision. You can see where mars was initially in the uncertainty region, and over time, as the uncertainty region became smaller and smaller, the planet moved first to the edge then entirely out of the region.

Much like Barack Obama and the New Hampshire Primary.

Oh well, maybe next time. Mars and Barack.
