Y can comets approach the Sun from any direction, but asteroids generally orbit close 2 the plane of ecliptic?

Answer 1

Actually, most short-period comets behave very much like asteroids and stay close to the ecliptic. Only those comets with orbital periods of thousands of years disregard the common orbital plane. This has led to the hypothesis that there is a spherical shell of cometary bodies (the Oort Cloud) extending perhaps halfway to Alpha Centauri. Opinions differ on how it formed. Some say it's the outer part of the original solar nebula that never got pulled into the accretion disk; but more think that the objects formed further in and got ejected by gravitational interaction with the larger planets.

Answer 2

It's generally believed that asteroids are the remains of a planet that once ezisted between Mars and Jupitor, but was pulled either apart by Jupitors gravitation or struck by some large object (such as the Schumacher-Levy comet that hit Jupitor a few years ago). As a result, most of the mass of that planet is still in the ecliptic plane.

Answer 3

ok: according to " Meteor Showers it happends when they appear in any direction like the West or South sky but no
Solar Eclipse at all because those Comets makes an complete Orbits around Earth, Moon & Sun only 1 time just that !"
