Exploration of the Solar System Pre-Conf. Act. Scale Model of the Solar System Worksheet Answers (HS)

NASA Glenn Videoconference: Space and the Solar System
Pre-Conference Activity Worksheet (HS): Scale Model of the Solar System Answers

Use the Planetary Fact Sheet (http://nssdc.gsfc.nasa.gov/planetary/factsheet/index.html) to find each planet's diameter and distance from the sun and complete the worksheet. Calculate the conversion factor by dividing the scale model size of the sun by the actual diameter of the sun. Use this conversion factor to calculate all of the scale model size values.

Celestial Bodies	Diameter (km)	Conversion Factor (m/km)	Scale Model Size
Sun	1,391,900	.0000007	1 meter
Mercury	4,879		3.5 mm
Venus	12,104		8.5 mm
Earth	12,756		8.9 mm
The Moon	3,475		2.4 mm
