# How much volume does our solar system take up?

And also how many Earths can we fit inside it?

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

Earth's volume is roughly 1,097,509,500,000,000,000,000 cubic meters (http://www.physlink.com/education/askexperts/ae419...

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

The solar system is often considered to extend out to about 50,000 AU from the sun. That's about 1.2 billion times larger than the Earth.

Volume of sphere = (4/3) pi R^3 = 7.2 × 10^27 Earths.
