Sometimes, NASA gets to have a bit of fun -- with asteroids. This fall, the agency will have a grand ol' time with one such object called 2012 TC4, which will whizz past us at a comfortable distance of about 4,200 miles (6,800 kilometers) at its absolute closest. Since the asteroid is pretty small -- only about 30 to 100 feet (roughly nine to 30 meters) across -- this is the perfect chance for NASA's Planetary Defence Coordination Office to test out its techniques.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
