Detailed explanation-1: -Comets that are in orbit travel from one edge of the Solar System until they reach the sun, then their path loops around the sun, and back towards outer space. Some comets have such long paths that it takes hundreds or even thousands of years to go around once.
Detailed explanation-2: -Comets are thought to orbit the sun in either the Oort cloud or Kuiper belt. When another star passes by the solar system, its gravity pushes the Oort cloud and/or Kuiper belt and causes comets to descend toward the sun in a highly elliptical orbit with the sun at one focus of the ellipse.
Detailed explanation-3: -Its very unlikely for a comet to become a satellite of an inner solar system planet. Much less likely than it is for an asteroid. Most asteroids are on fairly circular orbits, and so the relative velocity between asteroids and planets is quite low.
Detailed explanation-4: -The tail is pushed out by the Sun’s solar wind. What keeps the comet in motion and guides its path is the gravity from all the planets and stars it passes.
