I think the solar system as defined here extends out to the edge of the Oort Cloud.

> The outer limit of the Oort cloud defines the cosmographic boundary of the Solar System

> The Oort cloud...is a theoretical cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 au (0.03 to 3.2 light-years).
