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. 𝐴𝑐𝑡𝑢𝑎𝑙 𝐷𝑖𝑎𝑚𝑒𝑡𝑒𝑟 𝑆𝑐𝑎𝑙𝑒 𝐷𝑖𝑎𝑚𝑒𝑡𝑒𝑟 = 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.
The distance light travels in 1 year Light Year Light travels at 3× 10 8 𝑚 𝑠 NOTE : 𝑉𝑒𝑙𝑜𝑐𝑖𝑡𝑦= 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑡𝑖𝑚𝑒 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
