No. There is no comet or asteroid or meteor going to hit the Earth. Most of it is superstition.
An asteroid, because the orbits of the asteroids are nearer to the earth than the comets.
Among the Moon, Earth, Comet Halley, the dwarf planet Ceres, and Asteroid 12343, Comet Halley has the most non-circular orbit. Comet Halley's orbit is highly elliptical, taking it close to the Sun and then far out into the solar system, which is characteristic of many comets. In contrast, the orbits of the Moon, Earth, Ceres, and most asteroids, including Asteroid 12343, are more circular and less eccentric.

The scale of damage potentially caused by an asteroid or comet impacting Earth is known as the Torino Scale. It is used to communicate the potential threat level of near-Earth objects (NEOs) impacting our planet.
The name of the comet seen in 1986 is Halley's Comet. You can see it every 75-76 years, and is the only short period comet that is clearly visible to the naked eye from earth, and thus the only naked-eye comet that might appear twice in a human lifetime.
777,000 km....
A large comet or asteroid striking earth
Comets are difficult to predict; we currently know of no comets that will be visible in 2012, but new ones are discovered periodically. No asteroids that we are aware of will approach the Earth very closely before April 13, 2029, when the asteroid Apophis will come fairly close the Earth. (But it will miss.)
Probably an asteroid, meteor or comet.
An asteroid, because the orbits of the asteroids are nearer to the earth than the comets.
An asteroid
You usually get a crater, with surrounding damage.

"Meteoroid". If it actually hits the Earth's atmosphere, the streak of light will be a "meteor", and if the object survives to impact the Earth's surface then we call the remains a "meteorite".
