The scale below is designed to fit a hallway that is 180 feet long.
|Planet||Distance from Sun||Diameter|
|Mercury||1 ft. 9 in.||1.78 in.|
|Venus||3 ft. 4 in.||4.43 in.|
|Earth||4 ft. 7 in.||4.67 in.|
|Mars||6 ft. 11 in.||2.49 in.|
|Jupiter||23 ft. 9 in.||4 ft. 4 in.|
|Saturn||43 ft. 6 in.||3 ft. 8 in.|
|Uranus||87 ft. 6 in.||1 ft. 6.6 in.|
|Neptune||137 ft. 2 in.||1 ft. 5.8 in.|
|Pluto||180 ft.||1.1 in.|
On this scale, the sun would be a ball more than 42 feet in diameter. So it would not fit in a school hallway. And, on this scale, the nearest star to our solar system would still be 23,690,000 miles away!
