Measurements and Distances Study Guide

The units that we use to measure distances in space are:

• light years

• meters

• inches

• kilograms

Meters or miles should be used to measure:

• Distances on a planet

• Diameter of a planet

• Objects in space that are in our solar system

• Objects in space that are outside of our solar system
