That will completely depend on where the Earth and the comet
are in their respective orbits. No single answer is possible.
It is known as a light year.
Nobody in the real world.
Comets rarely cause damage to Earth as they are small icy bodies that burn up in the atmosphere or pass by harmlessly. However, if a large comet were to impact Earth, it could cause catastrophic damage due to the high speed and energy of the impact.
The speed of light is not always fixed at 299792458 m/s. In earth's atmosphere, the speed of light slows, though this is negligible. In water, light travels at 75% of c, and in a diamond, light travels at .40 c. C is the speed of light, rounded to 300,000 km/s.
Actually, the closest star to Earth is Sun which would be reached in a little more than 8 minutes.As for other stars, closest one is Proxima Centauri. You'd need to travel for 4 years and 2 months to reach it at the speed of light. You may or may not know that you have asked a delightful trick question. If I were traveling at the speed of light [impossible, of course] how long would it take me to get to earth's nearest star? From my point of view, the trip would be instantaneous. It would also be an instantaneous trip if I traveled to a destination 100 million light years away. Time completely stops at light speed. Observers on earth would conclude that the trip took me 8 minutes. We would all be right, within the scope of our individual frames of reference.
If you were to travel at the speed of light for a year, no time would pass for you, but approximately one year would pass on Earth.
Yes, a comet experiences intense heating and friction as it enters Earth's atmosphere, causing it to burn and create a bright streak of light known as a meteor or shooting star. This process is due to the extreme speed at which the comet is traveling through the atmosphere.

Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
Nobody in the real world.
If you traveled at the speed of light (a current impossibility), you would travel from Earth to the Sun in an average of 8 minutes. Or would you? I suspect that you would burn up well before the 8 minutes were up.
If any comet comes CLOSER to the Sun than Earth's distance from the Sun, its speed will be LARGER than that of Earth, which is 30 km/second.The exact speed will depend on how close the comet gets to Earth, and - to a lesser extent - on the exact shape of its orbit. If you know the orbital characteristics, you can get the speed using Kepler's laws. For a start, compare the orbit to Earth's orbit, using Kepler's Third Law.
it is a three wheeled car and the speed is745mphand it is called SSC
the only way i know how to time travel is that if you started at earth and went for a huge distance traveling at the speed of light (299,792,458 meters a second or 186,282 miles per second) then when you come back to earth you would have traveled in time. But the problem is we have nothing that can go near the speed of light and a lot of scientists say absolutely nothing can go faster then the speed of light.
100,000 km/hr the earth will become a comet or same as the sun
i seriously do not know... I'm just guessing that they are the same speed or so....
