It's theorized that all comets formed in the Oort cloud, which is a spherical cloud of comets roughly 50,000 AU from the sun. Out there are temperatures sufficiently cold enough to form the giant balls of ice we call comets
Edmund Halley, the second Astronomer Royal, observed it and predicted it would come back 75 years later. It did come back, he was no longer alive, but it was named Halley's comet at that time.
Edmund Halley and he used Isaac newton's new law of gravity to predict that the comet would return to Earth in 1758.
We believe that Comet Hale Bopp probably originated in the Oort Cloud, a distant region in our solar system.
It was discovered by two guys named Alan Hale and Thomas Bopp. It is traditional for comets to be named for the discoverer(s).

The Orbit of Comet Halley is an elongate ellipse, yes, but it does not orbit earth - it orbits the sun.
The first "certain" appearance of Halley's Comet is from 240 BC, in the Chinese chronicle Records of the Grand Historian or Shiji, which describes a comet that appeared "in the east and moved north".
Right now, Halley's Comet is a black cinder drifting through space beyond the orbit of Uranus.

Halley's Comet is currently a little beyond the orbit of Neptune.

Halley's comet appears because it is a comet that orbits the Sun. It as a highly elliptical (oval) orbit which makes it seem to fly out of the solar system and back.
No. The only way a comet could cause a catastrophe would be if it collided with Earth. The orbit of Halley's Comet keeps it at a safe distance from us.
No. It's a comet.
