Name: TG: Learning Target: I can describe the scale of the universe using models and the concept of light years Meter-Stick Solar System If the size of the solar system were reduced about six trillion times, Pluto on average would be about one meter from the sun. On this scale, the Sun itself will be about 0.2 millimeters (1/100 inch) in diameter. This is about the size on a pin. Directions: On 10 slips of post-it draw an arrow and write the name of a solar system body (listed below). Place a post-it slip on the meter stick at the distance of each planet. After determining the distance of the planets’ orbits to scale, look up the actual distance online. Solar System Body Distance to Scale (inches) Sun 0 Mercury 3/8 Venus 3/4 Earth 1 Mars 1 1/2 Jupiter 5 1/4 Saturn 9 5/8 Uranus 19 1/4 Neptune 30 1/8 Pluto 39 1/2 Actual Distance (miles) Exceeds: In this model, one inch equals one astronomical unit (AU) and one lightyear is a mile. Alpha Centuri is the closest star to the sun. It is about 26,395,632,000,000 miles away. How far would it have to be placed from the end of the ruler? (Hint: we have converted lightyears to miles before)
