I have read where the heliosphere is considered the biggest structure in our Solar System. Any comments?
Sorry this should have read Heliospheric Current Sheet. My mistake :)
It was referenced by Dr Tony Phillips (Spaceweather.com) in 2003 but if you Wiki Heliospheric Current Sheet you can read about it there!
My apologies.

Depends on what you mean by structure.

1. the arrangement of and relations between the parts or elements of something complex.
"the two sentences have equivalent structures"

2. a building or other object constructed from several parts.
"the station is a magnificent structure and should not be demolished"

I guess 1. is broad enough.

Yes, the heliosphere is huge. The Oort Cloud is larger, however, since it likely extends to about 60,000 AU or more.

The heliosphere, albeit thin, is the outer atmosphere of the Sun. This means all the planets are orbiting within the atmosphere of the Sun. I think that's pretty cool. :)
