149,597,870.7 length 1 Astronomical Units (AU).

The radius of the Solar System is now considered to be about 100 AU. This is the point where the the Solar Wind (from the Sun) meets the Interstellar Wind (thank you, Voyagers) called the heliopause (http://www.solarviews.com/eng/solarsys.htm). This gives a volume of 1.40e+40 cubic meters.

Dividing the Solar Systems volume by that of the Earth's gives about 12.78e+18 Earths. So, about 12 3/4 quintillion Earths would fill the Solar System.

edit: wilde all ready gave the equation for a sphere.

• The radius of the Solar System is estimated to be 1 light year. The equation for volume of a spehere is V = (4/3)*π*r^3

This gives us the volume of 4.18879 light years cubed, or 39,629,013,196,241.7 km^3
