Astronomers have since calculated the period of Comet C/1811 F1, also known as the "Great Comet of 1811" or sometimes "Napoleon's Comet" in honor of his military conquests, to have a period of 3065 years.
So, our distant descendants might expect it to return in the year 4876AD, assuming that in the year 2650 they don't send out a collector ship to bring it home and mine it to give the Moon an atmosphere. By then, we'll probably be able to do that. And we'll want the space. Just imagine the lunar Golf courses! :-)
Halley's Comet was last seen in 1986 and won't be visible again until 2061.
August 6, 2010. It will be back again November 21, 2013.
sometime in April of 2061
Halley's Comet was first recorded in 240 BC by Chinese astronomers. However, it was Sir Edmund Halley who calculated its periodicity in 1705, predicting its return in 1758. The comet was then named after him.
it s a comet which can be seen every 76 years ,it was last seen in the year 1986,march 8
That was Halley's Comet - it will not be seen again until 2062
We expect Halley's Comet in 2061.
No. It will be not be seen from Earth again until the year 2061.
Halley's Comet was last seen in 1986 and won't be visible again until 2061.
unsa man
because the comet is so far away theat you cant see it without a telescope
it was last seen in 1986 and wont be able to be seen again until 2061.
It showes ever 75-76 years so 2061.

Halley's Comet
You cannot see Halley's Comet once a year. It was last seen in 1986 and won't be seen again until 2061. There is typically a 75 to 76 year gap between when it is seen from Earth. During this time it is orbiting the Solar System and so at this point it is too far away to be seen from Earth. When it comes closer again, it will be seen from Earth.
