No comets are not visble on earth, every 76 years, only Halley's comet is only visible every 76 years
Any comet visible from earth is in orbit around the sun. If the orbit is closed (elliptical), the comet will return after some period of time. If the orbit is open (parabolic or hyperbolic), the comet will escape the solar system and never return to the neighborhood.

Comets tend to be visible for weeks or even months. They don't suddenly appear and then vanish again in a single night. So if there's been a comet visible recently, then it will probably be visible tonight; if there hasn't, there probably won't.There is some point, of course, at which a comet that was not previously visible becomes visible, and at which a comet that has been visible vanishes again. But what almost never happens is that a brilliant, spectacular comet appears overnight.There are nearly always a few comets visible through sufficiently powerful telescopes. The Related Links will take you to the Comet Chasing website, which lists all known comets currently theoretically visible to amateur astronomers (that is, you don't need a billion-dollar telescope to see them, though you may need a scope costing several thousand dollars to do so).
Halley's comet last passed through the inner solar system ... becoming bright enough to be visible ... in the mid 1980s. It's not expected to be visible again, even with significant optical enhancement, until some short time before 2060.
Sure. As a comet approaches the sun, the comet sheds some of its material, which trails behind it for millions of kilometers. It is this tail that is the most visible part of a comet. In fact, the word comet means "hairy star," referring to the long, streaming tail. In 1910, the earth actually passed through the tail of Halley's Comet.
lol it causes damage such as creating some crater,,,,,,,,,,,, it is very rare 4 a comet to hit earth lmao
As of October 12, 2014 there are no comets visible to the naked eye from Earth. There are several visible to telescopes, and a couple that are visible in binoculars, if you know where to look. A good website to go to if you want to know about currently visible comets is cometchasing.skyhound.com. The site is updated with names, approximate positions, and brightness; they even give some idea of what it will take (in terms of how large a telescope you need) to see it. Once you know the names of the comets that might be visible, you can check for further information on them so that you know exactly where to look on any given night.
The sun might explode some huge comet might it the earth
Most meteor showers are visible all around the world. Meteor showers occur when the Earth passes through the debris stream left behind from a comet; some comet trails are better mapped than others, and in some cases astronomers are able to predict with some accuracy exactly when the Earth will pass through the stream.Meteors are most commonly observed between midnight and dawn, when the "front" of the Earth passes through.
While there are some periodic comets whose orbits are known and whose returns are predictable, most of the comets that we see are unknown; their orbits are longer than recorded history.So there will probably be a comet visible in 2011, but we won't know it until someone "discovers" it in the night sky.
