Explanation:
Want to build a scale model
Solar System?
A blue
marble 1.4 centimeters (about half an inch) across would be a
good choice for a scale model Earth.
Since the
Sun is 109 times the diameter of Earth, a 1.5 meter diameter
balloon could represent the Sun.
But the
distance between the Earth and Sun,
150 million kilometers,
would translate to just under 180 meters (590 feet) at the same scale.
That would mean the completed project, including the orbits of the outer
planets, is probably not going to fit in your backyard.
Still, you might find enough room on a dry lakebed.
Check out this video for an inspirational road trip through the
Solar System to scale.
