Answer:

It depends on if you consider the oort cloud to be our solar system.

Explanation:

If you consider the oort cloud, our solar system goes out about 100,000 au. An au is the distance from the sun to earth and is about 7 light minutes (which means it takes light 7 minutes to get from the sun to earth).

If you don't consider the oort cloud, Eris is the farthest notable body with an orbit of about 68 au.
