Most cross orbits of planets which allows it to hit the planets easier. They do not go into a full orbit at all.
No. Comets orbit the sun. Many asteroids orbit the sun in between the orbits of Mars and Jupiter.
Most meteor showers are associated with the orbits of comets. When Earth passes through the debris left behind by a comet as it orbits the sun, the particles collide with Earth's atmosphere, creating the streaks of light known as meteors.
Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact. Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.
Scientist classifies these objects based on their sizes, shapes, compositions, and orbits. The major categories include dwarf planets, comets, asteroids, and meteoroids.
We generally believe that comets with orbits of 200 years or less, traveling in the ecliptic plane, come from the Kuiper Belt. Those comets with longer orbits, or that travel at angles to the ecliptic plane, come from the Oort Cloud.
Comets travel in highly elliptical orbits. See link for more.
they have long elliptical orbits
Comets. Periodic comets have highly eccentric elliptical orbits, with eccentricities.
No. Comets orbit the sun. Many asteroids orbit the sun in between the orbits of Mars and Jupiter.
Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.
Comets don't or it the earth, they are in long irregular orbits around the sun. These orbits can range from a few years to thousands of years.
Most meteor showers are associated with the orbits of comets. When Earth passes through the debris left behind by a comet as it orbits the sun, the particles collide with Earth's atmosphere, creating the streaks of light known as meteors.

All orbits are geodesic curves. Comets tend to have elliptical orbits ... as do planets, really; the degree of eccentricity (this is a measure of how "stretched" the ellipse is) just tends to be higher for comets.
