a different way to look at the size of the universe
This is taken out of "Astronomy", for Octboer 2001.
Lets say the Earth is a sphere that is 1 millimeter across (about the size of a period in a magazine). The sun would be the size of an american softball (4.3 inches or 11 cm) and the Earth woul dbe 12m(39 Feet). The moon would be .3 mm (.01 inches) wide and 3 cm (1.2 inches) from the Earth. Pluto would have a diameter of .18mm (.007in) and Jupiter would have a diameter of 1.1 cm (.43 in). Jupiter would be 62 m (203 ft) from the sun and pluto would be 450 m(1500 ft) away from the sun. The next nearest star is about 3100 KM (1900 miles) away. The milky way would be a disk about 97 million km (60 million mi) wide. The next nearest spiral galaxy, the Andromeda Galaxy, is about 1.7 billion km (1 billion mi) away. and finally all of observable space on this scale, would still have a radius of 9 trillion km (6 trillion mi) and a diameter of 18 trillion km (12 trillion mi). Now if this doesnt make u think about how big (or should i say small) we really are.
