Explanation:

Halley's Comet takes 75 to 76 years to complete an orbit around the Sun. Comets travel in elliptical orbits, usually going from a great distance away from the Sun (hundreds of millions of miles) to relatively close (just a few million miles) to it.This makes them visible from Earth, and every 75 to 76 years, as Halley's Comet approaches the Sun, it becomes visible in the night sky, looking a bit like a smudged star.
