Flight path of 2011 AG5. Source
Astronomers at NASA have determined that an asteroid, designated 2011 AG5, won't hit the Earth in 2040 after all. The 140 meter diameter rock orbits the sun along a path similar to the path Earth takes, so scientists were previously unsure of whether the asteroid would hit us or not. New observations show that we are safe from a potential extinction-level impact with this rock, and I for one am happy about that.
