How close do comet to the earth?
Comets have their own orbits in our solar system around the sun. They don't come close to the earth.
What are the types of comets?
Comets can be classified into two main types: short-period comets, which have orbits of less than 200 years and originate from the Kuiper Belt; and long-period comets, which have orbits of more than 200 years and originate from the Oort Cloud. Additionally, there are also sungrazing comets, which pass extremely close to the Sun.
Do comets travel in orbits with a shape similar to the planets?
No. The planets in the Solar System all have almost circular orbits, but the orbits of comets are highly eccentric (oval-shaped). This means that while the distance a planet is from the Sun is rather constant, the path of a comet means it comes close to the Sun, and then moves far away.
What objects travel in elongated cigar-shaped paths around the Sun?
Long-period comets such as Halley's Comet have elliptical orbits that stretch billions of miles out of the solar system and back again. Other comets have hyperbolic orbits that bring them close once but never again, or at least not for many millions of years.
Why the planets not colliding each other?
The planets in the solar system are in well-spaced out, stable, roughly circular orbits - they don't come close enough to collide with each other. Asteroids and comets, however, are on more elliptical, unstable orbits that often cross the orbits of the planets, and sometimes planets collide with asteroids and comets.
How close can comets get to the sun?
As close as they want - including crashing into it. Gravity and inertia control their orbits.
How do the orbits of comets differ from the orbits of most asteroids?
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.

Are there any comets other than Halleys comet?
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
What is the shape of the orbit a comet has?
The orbits of periodic comets and the orbits of planets have the same geometric shape.Every closed gravitational orbit is an ellipse. But the eccentricity of the cometary ellipsesare almost all greater than the eccentricities of the planetary ones.
Why do comets fall?
Comets do not fall. They orbit around the Sun in elongated orbits, with their paths often bringing them close to the Sun before they swing back out into the farther reaches of the solar system. This motion is due to the gravitational forces acting on the comet from the Sun.
Comets are considered to belong to the solar system if they?
They have to orbit the sun or orbit a planet. This means they are if they are in the Galaxy.
Do comets have highly elliptical orbits around the sun?
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.
