The Coma is a plasma composed of solar wind, interstellar dust, comet ions, comet dust & fragments that flows into the tail of the comet. The coma becomes bigger as comet gets closer to the sun and ranges from less than 1,000 to 100,000 kilometers in diameter.
The Tail is also a plasma composed of solar wind ,interstellar dust, comet ions, comet dust, & fragments that curves with the solar wind. The tails gets longer as the comet gets closer to the sun and range from less than million to 100 million kilometers in length (distance from the earth to the sun).
