  1. Pocket Solar System

  2. Making Our Pocket Solar System Step 1: Fold over the ends of your register tape so they are straight. Label one end “Sun” and the other end “Pluto/Kuiper Belt” Step 2: Fold the tape in half, crease it open it up again, and place a mark at the half-way point. Which plant does this mark represent?

  3. Making Our Pocket Solar System Step 3: Now fold the tape back in half, then half again. Unfold and lay it flat. Now you have the tape divided in quarters with the Sun at one end, Pluto on the other and Uranus in the middle. Place a mark at the quarter and ¾ mark. Which planets are represented by each of these marks? Reflection: Which part of the solar system has filled ¾ of your register tape? How many planets do we still need to represent?

  4. Making Our Pocket Solar System Step 4: Fold the Sun up to Saturn and crease it. Unfold and lay flat again. Place a mark at the 1/8 mark (between the Sun and Saturn. Which planet is represented by this mark? Reflection: If you take a look, you have the 4 gas giants and Pluto all on there. For the remaining bodies in the Solar System, you will only need ½ of the first 1/8th of the register paper (ie. that’s the inner 1/16th of the paper!)

  5. Making Our Pocket Solar System Step 5: Fold the Sun out to meet Jupiter to mark the 1/16th spot. A planet does not go here, but the Asteroid Belt does. Step 6: Fold the Sun to the Asteroid Belt mark and crease it. Place a mark on this fold (between the Sun and Asteroid Belt). Which planet is represented by this mark?

  6. Making Our Pocket Solar System Reflection: How many more planets do we need to place? Step 7: Fold the Sun up to meet the line for Mars. Leave it folded and fold that section in half. Unfold the tape and you should have three creases. Mark the remaining planets (in proper order) at each of the creases. Inner Planets Sun A.B Jupiter Saturn Uranus Neptune Pluto

  7. Making Our Pocket Solar System • Reflection Questions: • Are there any surprises with your results? • Can you estimate where Eris will be using the same scale as your model? At its closest approach, it is 38 AU all the way out to 97 AU from the Sun at its farthest point. • If your model were 1 meter, where would the nearest star be? (1m=40 Aus, Proxima Centauri is 4.3 light years from the Sun, and 1 light year=65,000 Aus) • How big would the Sun and planets be if your model were one meter long?

  8. Making Our Pocket Solar System • Reflection Question Answers: • Space is very empty in the outer Solar System. The inner Solar System is very crowded. • At 97 Aus, it would more than double the size of the model. You would need to add another one and a half meters to the model. • The nearest star would be about 7 kilometers or 4.2 miles away. • The Sun would be smaller than a grain of sand. You couldn’t see any of the planets without a magnifying glass on this scale!
