There are comets visible from Earth many nights, they are just too faint to be seen easily. So, there is a continuum of brightness -- comets from very faint to quite bright. The brightest are the spectacular ones that get in the news. Also, bright ones may be discovered not long before they are visible. If I remember correctly, McNaught, of January/February 2007, the second brightest comet since 1935, was discovered about 6 months before it came close.
HayleysComet will come about 2061!!!!!!!!!!!! It last came in 1986.
No, Halley's Comet was last visible from Earth in 1986 and is expected to return in 2061. It has an orbital period of about 76 years.
Approximately every 76 years 1986 + 76 = 2062
Probably several times. It is assumed that a third of Earth water came from comets and it was a comet that hit the Earth 65 million years ago and caused the dinosaur extinction.
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.
Halleys comet comes back around every 76 years.
You will if you live to be 62 or 63 years old.
early 2062
That is Halley's comet, named after English astronomer Edmond Halley,
No. in 1961 the comet was way out in the solar system, the recent close approaches were in 1910 and 1986 - non of there were as close as 10 miles from the nucleus, although Earth did pass through the comets tail in 1910.
It takes 75 years
76 years

No, a comet will NOT hit earth in 2012.
