How many meters (m) are there in 56 kilometers (km)?
How many centimeters (cm) are there 2 meters (m)?
How many millimeters (mm) are there in 3 meters (m)?
Create a scale conversion factor
If the Sun were scaled to 50 cm, how many kilometers are represented by 1 cm?
The diameter of the Sun is 1,390,000 km.
There are _______ kilometers per 1 centimeter

The Milky Way – Our home galaxy
There are about 100 billion stars in our galaxy. We can see about 4000 on a typical clear, dark night.
Light Year
Light travels at NOTE :
A light year is The distance light travels in 1 year
This is equal to 9,460,730,472,580,800 meters (exactly)≈ 5,878,625 million miles ≈ 63,241.1 astronomical units
Where are we in the Milky Way?
