The orbital period of Halley's Comet is about 75.3 years.
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.

It takes roughly 75 years for Halley's comet to come by the earth. All comets orbit the sun, but they do not all originate from the same place, which accounts for their paths and how long their individual orbit takes.
