There are several known meteor showers that occur more-or-less regularly during the year. They occur when the Earth passes through the dust trail left behind by a comet.

That depends on what you call 'long' or 'short'. Halley's period is in the neighborhood of 75 years, give or take a few years. Since that's short enough for two perihelions to occur within a single human lifetime, I guess it ought to be considered a short period.
