Why did the last halley comet happen?

Answer 1

Halley's comet is really just an icy rock that orbits around the sun just like the planets do. The difference is, instead of it taking just one year to go around the sun like Earth does, it swings way out to the outer edge of the solar system on every orbit, and takes 75 years to make a complete circle.

The only time we ever see it is when it comes close to the sun, in Earths neighborhood. It spends all the rest of that time way out in space zipping along in the dark.

The last time this happened was in 1986. Halley's comet isn't due back until 2061!

Answer 2

why comets happen is the dust that is left over and ice that is no longer needed in the solar system that will not have nothing to do with the sun and that will no longer be needed also,it is soooo much of dust that is piled on that wiil make a comet well thanx

Answer 3

Halley's Comet returns approximately every 76 years due to its elliptical orbit around the Sun. Its last appearance was in 1986, and it is predicted to return in 2061. Comets like Halley's are remnants from the early solar system and provide valuable information about its formation.

Answer 4

Halley's comet has not crashed. It is well known because it is a bright and very predictable comet.
