Review Space-3

Which of the following is a difference between a meteor and a comet?

  1. Meteors are mostly made up of ice.

    No. Meteors are made up of rock or iron, Comets are mostly made up of ice.
  2. Only comets have a visible tail.

    No. A meteor is a meteoroid that has entered our atmosphere. As it burns, it also produces a tail.
  3. Meteors seem to move faster because they are closer.

    Yes. Meteors are entering our atmosphere, so they are much closer to us that a distant comet. That makes them seem to move much faster.
  4. Comets are smaller than meteors.

    No. Meteors are small, often the size of a grain of sand. Comets are much larger.
