About 75 or 76 years depending on how close it got to the Sun and the large planets (Jupiter, Saturn) last time around.
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.
Halley's Comet returns once every 75-76 years.
The same as the Earth

Comets typically take hundreds to thousands of years to return to the inner solar system and replenish Earth with water. The specific time it takes for a comet to return depends on its orbital period and distance from the Sun.
That varies completely from comet to comet.
The orbital period of Halley's Comet is about 75.3 years.
It takes 75 years

Halley's Comet returns once every 75-76 years.
There are no data with which to answer that question, because no comet has ever yet been observed in orbit around a moon.
