Answer:

  1. The distance across a galaxy group is usually a few hundred thousand light - years.
  2. Stars cluster together to form galaxy groups.
  3. Galaxy groups typically contain several hundred galaxies.
  4. Galaxy groups are mostly composed of empty space.

Brief Explanations:

These are well - known facts in astronomy. Galaxy groups have large spatial extents measured in light - years. Stars first form galaxies which then cluster into groups. Galaxy groups have multiple galaxies and vast amounts of empty inter - galactic space.
