1. SCALE ON A STRING
Scale model of the Solar System
The table below lists each of the planets for your scale model. If the distance from the Sun to the Earth is 2 feet in your scale
model, compute the rest of the values below.
Distance from Sun (Miles) Distance from Sun (Feet)
Mercury 35,983,610
Venus 67,232,360
Earth 92,957,100 2.0
Mars 141,635,000
Jupiter 483,632,000
Saturn 888,188,000
Uranus 1,783,950,000
Neptune 2,798,842,000

2. SCALE ON A STRING
Scale timeline of the universe
The table below lists each of the big history thresholds for your scale model. If the length of your string is 100 feet, compute the
rest of the values below.
