It was discovered by Alan Hale and Thomas Bopp in 1995.

Halley's comet - which returns to our solar system approximately every 75 years - is one example, named after it's discoverer Edmund Halley. Another notable example is Shoemaker-Levy 9. It was observed orbiting the planet Jupiter, but the orbit was decaying - leading to the prediction that it was to crash into Jupiter's surface.
The comets come from the Oort Cloud named after Jan Oort who suggested in 1950 that they originated from a common location in the Solar System.
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.
By themselves, comets are not really important. Even the most impressive comet, like Hale-Bopp, is a visual spectacle only. But the POTENTIAL for a comet - to strike the Earth directly and cause untold devastation - is far more significant. Right now, if we were to see a comet aimed at the Earth, there is very little that we could do about it, other than stand there and die. The threat of a comet impact, like the ones that have devastated our planet several times before, ought to be enough spur us all into looking for ways to protect ourselves from the inevitable time that it WILL happen again.
A comet's tail points away from the sun
its the point of origin
A comet has the most potential energy at its farthest point from the sun (aphelion) in its elliptical orbit. At this point, the comet's gravitational potential energy is maximized due to the distance from the sun being at its greatest.
