# How big is the Solar System?

How big is the solar system?

By "big", I guess I mean "wide", i.e. how far away from the Sun is the farthest object that is considered part of the Solar System?

I've checked Wikipedia's pages on the Solar System, as well as Pluto, the Kuiper belt, and Trans-Neptunian Objects, but couldn't see the answer.

Hi Keith, yes, I looked at that page, but couldn't see the answer, despite clicking through to Pluto, Kuiper Belt, and Trans-Neptunian Object. –  gkrogers Feb 7 '12 at 3:33
@gkrogers We strongly encourage providing your reference routes and previous efforts in research as part of your question, otherwise we're A) left to assume you didn't research and/or B) provide answers that cover from a baseline. These points coupled can often make answering a much more laborious process when information is 'missing'. And, well, with it we then know you're learning to fish, not just begging. –  Grant Thomas Feb 7 '12 at 14:17
@Mr.Disappointment OK, I've included references to where I looked before I asked here. –  gkrogers Feb 7 '12 at 22:32
@gkrogers Thank you for taking the time to do so. (: –  Grant Thomas Feb 7 '12 at 23:06
