Is a meteor lined up with the earth?

Meteors of varying sizes hit the Earth ten thousand times a day. Most of them are the size of a grain or sand or smaller; some are as big as a grain of rice. A few are the size of a soccer ball.

And once in a while, something bigger hits. Every few years, something the size of a car hits the Earth; every few centuries, something the size of a house hits us. Every few million years, something the size of a mountain hits, causing massive devastation.

It WILL happen again, but we don't know when. Nothing particularly hazardous is currently on the radar.

There is a moderately large asteroid called "Apophis" which will make a close approach to Earth on Friday, April 13, 2029, but will certainly miss. It will be back seven years later, on Friday, April 13, 2036, when it will very probably miss. The difference between "certainly miss" and "very probably miss" causes NASA scientists some worry, but as they get a better and better track of Apophis, the odds of a collision are going down.
