Scale of the solar system — Homework

Use the ratios: Sun diameter is about 110 times Earth's diameter; Earth-Sun distance is about 107 times the Sun's diameter.

  1. 1.If the Sun is modeled as a 50 cm ball, about how big should Earth be modeled (use the ratio of about 110)?
  2. 2.Using that same 50 cm Sun model, about how far away should Earth be placed (use the ratio of about 107)?
  3. 3.Why does an accurate scale model of the solar system need so much empty space between the Sun and Earth?
  4. 4.Explain what is wrong with a classroom poster showing the planets' correct relative sizes but placed close together for space reasons.
  5. 5.Choose an object to represent the Sun and calculate the correctly scaled size and distance for Earth, showing your work.
