In prehistoric times large objects have caused big craters. Whether before impact these would have appeared like comets is a matter for debate.
A comet is a celestial body. Anything that enters the earths atmosphere and/or strikes the earth is deemed a meteorite

Planet's orbit are nearly circular What shape is a comet's?
The shape of a comet's orbit is called an ellipse. This shape is a sort of narrowed circle and comets move in this shape around the sun.
What do you call to the point where the earth is fastest from the sun?
Aphelion is the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
What point in a planet's orbit is closest to the sun?
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
Why don't the rocks from tail of a connet fall on the earth?
Sometimes they do; that's what a "meteor shower" is. The point is that all of the rocks and dust given off by a comet, and the head of the comet too, travel the way gravity and the light pressure of the Sun force them to. The head of the comet is freely falling towards the Sun. (if a comet gets close enough to a planet, the gravity of the planet becomes significant, and sometimes the comet will collide with the planet; look at Shoemaker-Levy 9, which hit Jupiter in 1994.) As the heat of the Sun begins to melt the ices of the comet, gas and dust escape from the comet. Because the gas molecules and dust particles are very light, the pressure of the Sun's light pushes them away from the comet; this forms the "tail" of the comet. Over the course of thousands of orbits, the gas and dust spreads out to fill in much of the orbit of the comet. Where the Earth's orbit intersects the comet's orbit, we see annual meteor showers.
What would happen if the moon rotated?
It would spin out of earths orbit. And most likely hit a planet, star, comet, or keep on going.
Where does a comet have the most potential energy?
At its aphelionThe aphelion is the point in the orbit of a planet or comet that is at the greatest distance from the sun.
How is the orbit of a planet different from the orbit of a planet?
A planet typically has a more regular orbit, staying closer to the same distance from the sun. A comet's orbit will be more elliptical, going very far away and then coming really close.
Is a comet a moon?
No. A comet orbits a star such as the sun. In order to be a moon it must orbit a planet or some similar body.
Planet's orbit are nearly circular What shape is a comet's?
The shape of a comet's orbit is called an ellipse. This shape is a sort of narrowed circle and comets move in this shape around the sun.
What is a loose icy body with long narrow orbit?
The planet furthest from the sun
Do comets have the power to destroy a planet?
No. A comet can leave a large crater and, in the case of Earth, cause a mass extinction, but a comet cannot destroy a planet or even significantly change its orbit.
What is the name for body of orbit around the sun?
Planet, planetoid, moon, asteroid, meteor, comet
What forces keep the comet in orbit around the sun?
A comet stays in orbit by the gravitational pull of other planets/ objects in space but pulled to a planet because of the stronger pull gravity.
What do comets orbit other then the sun?
The comets in our Solar System orbit our Sun. Presumably, a comet could be trapped by a planet, so that it orbits that planet; and presumably, there are also comets around other stars.
What do you call to the point where the earth is fastest from the sun?
Aphelion is the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
How do you use the word Aphelion?
Aphelion is the point in a planet's or comet's orbit where it is farthest from the Sun. The Earth's aphelion is 152,098,232 km.
Will a planet or comet be moving faster in its orbit when it is closer to or farther from the sun?
Planets and comets move faster when they are closer to the sun.
