The comet's size changes depending on how close it is to the sun and the location. There's no real set size range.
A comet be able to be of sun size.
big
The comet west is estimated to be about 37 miles in diameter.
Depends on the comet. Size varies. But they are usually smaller.
actually a comet will make a bigger tsunami than an earth quake because it depends on how big the comet is so obviously if its a mini comet about the size of a fist its not going to do any affect but a comet like the size of Texas it would make a Mega Tsunami and once there was a Mega Tsunami the size of a city! and it flooded it completely.
It varies- it entirely depends upon the size of the comet, they are all different and there's no standard size for them. They can be as little as about 100 feet across, whilst the big ones can have a diameter of a couple of miles.
It is aproximitaly40 km in diameter
About the size of Texas.
it depends on the size of the comet if it was small it would do about 5o/ out of a 1000 on earth if it was a very big one it would do about 989/ out of a 1000 so it depends on size
A comet is just the size it is, and starts it's journey as a comet when some gravitiaional influence nudges it out of the Oort Cloud in in toward the solar system. Every time a comet makes a pass around the sun, it gets smaller, as it gradually is "boiled away" by it's passage around the sun. So all comets have a finite life span, once they are caught into the sun's orbital pull.
An asteroid
a comet estimated to be roughly the size of mars
