How many earth years does it take a comet to orbit?
Halley's Comet takes 73.5 years to orbit the sun but every comet is different just like planets.
How many years does it take for Haley's comet to orbit the sun?
76 years.
What does a longer orbit mean?
Having an elliptical orbit means there is a point for each comet where it is a comet's orbit can be changed over many years by gravity, until it is long and thin.
Approximately how many years does it take Halley's comet to orbit around the sun?
about 76 years
How long does it take for a normel comet to orbit the sun?
Define "normal" - it varies from a few years to many centuries.
How many years did it take Hayleys comet to orbit the earth?
Hayley's Comet does not orbit the Earth. It has a long elliptical orbit around the Sun, and gets as far out as the orbits of Neptune and Pluto (35.1 AU) , only to return to the inner solar system every 75-76 years. (Its orbit is perturbed by some planets.) It last reached perihelion (closest to the Sun) in 1986, and it will not return until 2061.
How often does a comet appear and why then?
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.
Why are you able to see a certain comet one but not again until many years later?
The orbits of comets are elongated ovals that take the comet around the sun and then far out beyond Pluto. We can see them only in that part of their orbit which brings them close to the Earth
How many years does it take for haleys comet to come bythe earth?
It takes roughly 75 years for Halley's comet to come by the earth. All comets orbit the sun, but they do not all originate from the same place, which accounts for their paths and how long their individual orbit takes.
How many years does Halley's comet take to reappear?
It takes some 75 to 76 years for Halley's Comet to orbit the sun. It last appeared in the inner Solar System in 1986, and will next appear in mid 2061. A link is provided to the Wikipedia article on Comet Halley.
How did Edmond Halley predict that Halley's comet was coming back again?
He didn't discover it. He did some calculations that suggested that a certain comet, seen during his lifetime, and three comets seen many years before, had the same orbit, and therefore were all probably the same comet. He also predicted that this comet would return in a certain year in the future. It did and it was named as Halley's comet, in his honour.
How many years it takes for Haleys comet to come around?
Halleys comet comes back around every 76 years.
