a comet that passes around earth every 76 years. It has gone by in 1835, 1910, 1986, and will return in 2061
Its the center of Halleys Comet that is practically the middle wich is called the nucleus
A comet.
yes.
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
Because comets cannot decide when they will be visible. It was a natural phenomena and remains so. Comets have a 'year' as do all solar objects. Halleys comets year happened to coincide with the battle. It was a coincidence, nothing more than that.
A cloud of gas surrounding the nucleus.
Nucleus coma tail
yes.

Yes.
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.

comets
The tail, the coma, and the nucleus.
1 - Halley's 2 - Lovejoy 3 - Hale-Bopp 4 - Ison 5 - Shoemaker-Levy 9 Note: Obviously that's a matter of opinion to some extent. I would have a different list. See "related link" below for a list of some famous comets. Note: Unfortunately, the photo and caption for the "eclipse comet of 1948" is wrong in this link.
The solid portion of a comet or more accurately, the source for all the gases and dust that make a comet visible to us, is called the nucleus.
