Halley's Comet is a famous periodic comet that is visible from Earth every 75-76 years. It is named after the astronomer Edmond Halley who successfully predicted its return. The last time Halley's Comet was visible from Earth was in 1986, and it will next be visible in 2061.
No comets are not visble on earth, every 76 years, only Halley's comet is only visible every 76 years
At the end of December 2011, the following comets are all brighter than magnitude 12 as seen from Earth: -- C/2009 P1 Garradd -- P/2011 Y1 Levy -- C/2011 W3 Lovejoy -- 21P Giacobini-Zinner
It is challenging to predict which comets will be visible from Earth by 2100, as new comets are discovered regularly. However, some of the periodic comets that are expected to return within this timeframe include Comet Halley (2061), Comet Hale-Bopp (c. 4385), and Comet Swift-Tuttle (2126).
In mid-September 2011, the following comets are brighter than magnitude 12 as seen from Earth: -- P/2007 R5 SOHO -- C/2010 X1 Elenin -- 45P Honda-Mrkos-Pajdusakova -- C/2009 P1 Garradd
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.
Hopefully some serious advances in medicine come about, as we will need them to view this comet again. It is estimated that this comet will not return for another 29,500 years.
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
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.
