Depends on the planet or moon. Re-ask your question with the missing information.
I think there are called craters. I thinks so dont take my word for it.
That varies completely from comet to comet.
The orbital period of Halley's Comet is about 75.3 years.
Halley's Comet takes 73.5 years to orbit the sun but every comet is different just like planets.
Air and water will gradually transform the craters, making them hard to see. The craters will be "washed away". On the Moon, it takes much longer for a crater to become "washed away".Air and water will gradually transform the craters, making them hard to see. The craters will be "washed away".

Assuming the comet is far away in the outer solar system, it would take light approximately 8 minutes to reach Earth from the Sun, and then more time to reach the comet depending on its distance. Traveling at the speed of light, it would take a few minutes to several hours or more to get from Earth to a comet, depending on its specific location in space.
It take exactly 75 to 76 years.
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
Halley's Comet returns once every 75-76 years.
Halley's Comet orbits the sun, not the earth, roughly every 76 years.
There are no data with which to answer that question, because no comet has ever yet been observed in orbit around a moon.
There is no such cheat code for the car comet.
