one au or astronomical unit (distance from earth to sun) is 149597870700 meters
a billion is 10^9
so300 billion is 300000000000 kilometers, so times 1000 again to get meters to get
300000000000000 meters
solar system distance=au times x
solar systerm distance/au=x
300000000000000/149597870700 =x
2005.3761366805336487987860110632=x
about 2005 AU s to get to the solar system
