The Leonids happen every year, but on some years, they're brighter and fall at a greater frequency. It all depends on exactly how Earth passes through the Leonid stream from Comet Temple-Tuttle, which passes near our orbit every 33 years. However, even if the comet isn't there, its dust trails from previous orbits still are, and the big Leonid years are the years when we'll be passing through a more recent trail. Last year was supposed to be a Big Year because we passed through 2 dust trails. If this year is anything at all like last year, it should be a heck of a sight...

Now, if only there weren't that pesky nearly-full moon at the same time.
