Asked by Sunny
1. If the Earth were the size of B-B (with a radius of about 0.2 centimete), how big would the Sun be? How big would the Milky Way be?
2. Imagine building a model of the Solar System on your campus. Work out the diameter and spacings of the planets in millimeters and meters respectively.
The Sun's diameter is 109 times bigger than the Earth's.
so 109 times 0.2 = ?
The milky way is
6x10^17 miles in diameter
Try doing the math.
