Distances in Space

Lightyear is the measurement of...

• the speed of light

• the amount of time light can travel one parsec

• the distance light can travel in one year

• the distance light can travel in one second

What is the point of making the scale model of our solar system in the lab?

• To compare the relative distances between the planets in our solar system.

• To compare the relative sizes of the planets in our solar system.

• To show how big our solar system is compared to other solar systems

• To show the path of the orbits of all the planets in the solar system
