Yes, there are many comets that have been seen by people.

Yes, "Sozin's Comet" will be shown on Nick again.
Halley's Comet is unlikely to ever pose a hazard to the Earth. As such, it has no ecological significance.
A Comet is a body in perpetual orbit. A Meteorite is a body which enters the Earth's atmosphere. It is unlikely that Halley's Comet will ever crash into the Earth.
There is no possible way of smelling a comet without either a) it crashing to earth and it killing everyone or b) you landing on a comet in your lifetime to "sniff" it. so the answer is unknown because no one ever smelled a comet
I don't think so
i have no clue what so ever :D
Comet C1847 T1, "Maria Mitchell's Comet", was on a hyperbolic trajectory and is not expected to return to the inner solar system.
Aang did not die in Sozin's Comet. He defeated Firelord Ozai and more or less lived happily ever after.
