While researching a topic, a student has taken the following notes:
- In Göttingen, Germany, there is a true-to-scale model solar system called the Planetenweg Göttingen.
- The scale model Earth is 0.65 cm in diameter.
- The scale model Sun is 70 cm in diameter.
- The actual Sun is roughly 1.39 million km in diameter.
- The actual Earth is roughly 12,742 km in diameter.
- The Sun is over 100 times bigger than Earth.
