Arrange the following in order of decreasing size
clusters, stars, universe, planets, asteroids
universe, clusters, stars, planets, asteriods
Used for measuring distances in space; also the distance light can travel in one year
Explain why the light we see from star in the night sky may be hundreds or thousands of years old when it finally reaches Earth
This is because light takes time to travel from the star to Earth
