### Relative Distance between Planets

1. Cut out circles for each of the planets(PART 1) 2. Place them apart by converting astronomical units to a 10 centimeter/AU scale. an astronomical unit, or AU, is a simplified number used to describe a planet’s distance from the sun. It is a unit of length equal to the average distance from Earth to the Sun, approximately 149,600,000 kilometers 3. Take a picture of your model 4. Complete PART 2 5. Record your voice to explain the differences in distance (AU) PART 1 Sun 0.0 AU=0 cm Mercury 0.4 AU=4 cm Venus 0.7 AU=7 cm Earth 1.0 AU=10 cm Mars 1.5 AU=15 cm Asteroid Belt 2.8 AU=28 cm Jupiter 5.2 AU=52 cm Saturn 9.6 AU=96 cm Uranus 19.2 AU=192 cm Neptune 30.0 AU=300 cm PART 2 Sun: stands at the edge of the area Mercury = 1 step from sun Venus = 2 steps from sun Earth = 2.5 steps from sun Mars = 4 steps from sun Asteroid belt = 8 steps from sun Jupiter = 13 steps from sun Saturn = 24 steps from sun Uranus = 49 steps from sun Neptune = 76 steps from sun Kuiper belt = 100 steps from sun
