"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".
If you mean here on earth, yes - for one, the "Tunguska Event" in Siberia early in the 20th century is believed by many astronomers to have been caused by a chunk of Comet Encke breaking off and falling into earth's atmosphere. The "K-T Event", credited with the end of the dinosaur area may have been cause by a comet impact, though an asteroid is usually believed to have been the cause of that. The fact that water exists in huge quantities on the earth is also believed by many astronomers to have come from multiple comet impacts early in earth's history.
All orbits are ellipses. Some orbits, like the orbit of the Earth around the Sun, are almost (but not quite) circular. Other objects, like the Moon or Mars, have orbits that are more distinctly oval shaped.Comets have elliptical orbits with very high eccentricity; they are stretched so that they come quite close to the Sun, but still go dozens or hundreds of AU away. Some comets are less severely eccentric. Halley's Comet, for example, only goes out to about 30AU with a period of 76 years, while Comet Hale-Bopp has a period of closer to 2200 years.
In Comet Kermillian candace says "When I'm 88 you'll be so busted" Ferb says "you'll be 88 and ½." The comet kermillian comes every 73 ½ years. 88 ½ - 73 ½ 15
The rocky, gritty material in a cometary nucleus is probably much like a solid asteroid in chemical profile. But most asteroids are solid, barren rock - the comet has a large percentage of ices in it.
That is Halley's comet, named after English astronomer Edmond Halley,
Yes. A comet or asteroid can break up to form a chunk of rock called a meteoroid.
Yes. A comet or asteroid can break up to form a chunk of rock called a meteoroid.
An asteroid-sized chunk of rock with a tail would be a comet.
a meteroid or comet i think
An asteroid or perhaps a comet depending on the orbit the object takes.
Scientists usually refer to this as an asteroid, not a comet. It's the asteroid that caused the Chicxulub crater.
In Japan, the superstitions that are related to comet and asteroid is that it is death calling. People therefore are usually afraid to see the comets and asteroids.

No. For one thing, Halley's comet is a comet, not an asteroid. The largest asteroid is Ceres, which is far larger than Halley's comet.

You usually get a crater, with surrounding damage.
