For the last 4.5 billion years Halley's Comet has orbited the Sun.
The last time it was visible to the naked eye on Earth was 1986.
The next near pass is likely to be about 2061.
Depends who you mean by "they". The last time Halley's Comet was close enough to the sun and the earth for ordinary people to see it with our naked eyes was in 1986. After that, as it headed away from the sun again, astronomers tracked it telescopically for almost another year. The Halley Committee has scheduled the comet's next appearance for 2062.
the last time haley's comet was seen it was seen on august 26,2006
no the last time was seen like in 1986 and the next time it might be in 2062or 2062
The last time Halley's comet came by Earth was February 9, 1986.
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.
33 years.
You can't see Halley's Comet at any time of the year now. It was last seen from Earth in 1986 and won't be seen from Earth again until 2061. It orbits the Solar System, taking about 75 to 76 years to do so, so it can only be seen about that often from Earth.
it is the time when the tail is facing the north of the other comets like this <halleys tail is north of the other comets when they go > this way

Halley's comet is in orbit round the sun. Its orbit time is about 75 years, but as the orbital path is long and narrow, most of that is spent far out where we cannot see it. We see it for a few months when it is near the sun.
Halley's Comet has never been 10 miles above Earth. It is always millions of miles from us, even when closest to us. It was last visible from Earth in 1986. It will next be visible in 2061.
Yes, the time it takes for a comet to complete 1 orbit is called a period.

That is Halley's comet, named after English astronomer Edmond Halley,

halleys comet will return in 2061.
It can be seen every 75-76 years. The next predicted perihelion of Halley's Comet will be 28 July 2061.
Halley's Comet or Comet Halley (officially designated 1P/Halley) is the most famous of theperiodic comets and can currently be seen every 75--76 years. Halley's Comet last appeared in the inner Solar System in 1986, and will next appear in mid-2061.
