You can only see them at night, you can only see them if Earth is facing that way and you can only see them if they come near Earth.

∙ 14y agoComets have very large orbits that span billions of lightyears. The comets that do come close to earth do so because the sun or another large planet in the solar systems' gravity has caused an effect upon the comets large orbit. The comet orbits one of these large bodies in addition to other stars or planets elsewhere in our galaxy. A comet may have an orbit that will not bring it back to our solar system for 100 years or much, much more!! An orbit will be the same over and over again until some external force is introduced that has enough mass (thus enough gravitational force) to change the orbit.
Lets say that on your way home from work you have to stop off at the gym, the grocery store and then the pharmacy. You do this same routine each day. Although these locations are located all over the town you still make the trip. It wont be very long until you get back to your starting point and begin the trip or orbit over again, unless you get an emergency call that you have to pick up your mother from the Drs office every day. This will change your orbit. Now, lets say someone else has to stop off at 10 locations each day all over the state. That's a larger trip or orbit. It will take longer for him to get back to the starting point to start over. Now lets says someone has to stop of at 50 locations all over the country. It will take him longer to reach these destinations and longer than the first 2 people to reach the starting point and start over. Finally someone needs to make 250 stops all over the world. It will take him the longest to complete his orbit and this will take him the longest to return to the starting point to begin again.
This is, admitably, a bad analogy, but it can give you a hint that these orbits can be very small and very large and they will stay the same unless something changes like a stellar body is added or removed from contributing a gravitational pull upon the comet.

∙ 13y agoComets are believed to appear in the skies when a star "falls" or dies. It is a frozen mass that "glows" when it becomes warmer and produces the tail that we see in the sky.

∙ 15y agoComets can be seen from Earth only part of the time, when they are close enough to the Sun.

∙ 14y agoMost likely depends how far away it is from the earth. All it really is, is a burning rock flying through the sky .

How do comets come toward the earth?
From gravitational attraction.
When comets occasionally come close to the sun creating a bright?
Earth
All meteorites collected on Earth come from asteroids or comets?
False.
How do comets vaporize?
When comets come in contact with the earth's atmosphere, the air resistence and the action of gases wears it off, so ultimately it disappears.
Has a rogue planet ever come near earth?
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
Do comets come near earth?
yes
How do comets come toward earth?
Comets come toward earth during their orbits. They are drawn toward the sun by gravity and sometimes cross earth's orbital path in the process.

How has comets helped the study of space?
Comets come from the coldest parts of the universe and contain ice and organic materials. Scientists believe that impacts from comets on earth are responsible for contributing to organic materials and possibly life on earth.
