Which of the following is arranged from biggest to smallest?

  1. Galaxy, universe, constellation, solar system

  2. Universe, galaxy, constellation, solar system

  3. Universe, constellation, galaxy, solar system

  4. Galaxy, constellation, universe, solar system

Think about it, and when you think you know the answer, then continue.

The answer is 2.

  1. The universe is the largest, containing all galaxies, constellations, and solar systems.
  2. Galaxies come next. Each galaxy contains millions of stars.
