Some comets that have appeared in the last 25 years are Hale-Bopp, Hyakutake, Shoemaker-Levy 9, Swift-Tuttle, and Tempel 1. C/2006 P1 McNaught was the brightest comet in the last 25 years.
Comets are remnants from the early Solar System, composed of ice, dust, and rock. They have been observed for thousands of years by various cultures and have often been seen as omens or celestial signs. Halley's Comet is one of the most famous comets, known for its periodic appearances every 76 years.
"Periodic" comets reappear at predictable intervals, such as Haley's Comet. Some comets are never seen again. A few crash into the Sun and are destroyed; a few crash into other planets, such as the Shoemaker-Levy comet that hit Jupiter. Many comets have such long periods, in terms of thousands of years, that no records exist that anyone ever saw them before.
As objects visible to astronomers with telescopes, it is a rare time when some comet is not visible in the sky, at some place in the world. But as far as large, naked-eye comets, the last one was Comet Hale-Bopp, which reached maximum brightness in April of 1997. It will not return for about 2500 years. New comets are being discovered all the time, but there is no way to predict when or if a large, naked-eye comet will be seen again. We are reasonably sure of the return of Comet Halley, but that will next be in 2061.
it s a comet which can be seen every 76 years ,it was last seen in the year 1986,march 8
It depends on where the comet is in relation to the earth and sun, but not many comets would be bright enough to be seen before dusk or after early dawn.
Do you mean Biela's comet? Last seen in 1852.
There is no set number, because new comets are discovered all the time. Not all comets that are discovered will be visible with the naked eye.
Halley's Comet, a periodic comet that appears roughly every 75 years, is present in space. It is one of the most famous comets and was last seen in 1986.
Comets were seen shooting from the firery pit known as your mother's vagina.

Comets have been seen and studied by people for thousands of years. Edmond Halley predicted a comet to return in 1705 which is why we call it Halley's Comet or Comet Halley.
comets seen"
It's impossible to answer that, but I can tell you whenit was seen: right now.There are nearly always at least a few comets visible from Earth through telescopes.
over 1500 coets have been seen over 200 years we wont see comet hale bop until year 4395! a comet is made from ice dust and rock! these are called dirty snowballs
About 15-20 years, then they begin falling off. They can be re-attached initially, but will continue falling off over the years.
Many comets orbit the sun. How often we see them depends on their orbits. Halley's Comet, the most famous one, returns about every 75 years. It was last seen in 1986 and is expected again in 2061.
Depends on the type, amount of use, upkeep & maintenance. Most should last at least ten years. I have seen some that lasted well over twenty. Depends on the type, amount of use, upkeep & maintenance. Most should last at least ten years. I have seen some that lasted well over twenty.
