Is the heliosphere inside or outside of the Oort Cloud?

Voyager 1 has been reporting events at or near the boundary of the heliosphere since 2010 when it was 113AU from the Sun. read more

The hypothesised Oort Cloud starts somewhere between 2,000 and 5,000AU from the Sun and may extend to about 50,000AU. The heliosphere is therefore at least an order of magnitude smaller than the inner boundary of the Oort Cloud, and over two orders of magnitude smaller than the Oort Cloud overall. read more

The Kuiper belt and the Scattered disk are widely believed to lie in the space between the outer planets and the Oort cloud, but not to reach all the way out to the Oort cloud (apparently due to resonances with Neptune and a scarcity of sighted object much outside the 1: 2 resonance orbit). read more

The Oort cloud (/ ɔːr t, ʊər t /), named after the Dutch astronomer Jan Oort, sometimes called the Öpik–Oort cloud, is a theoretical cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 50,000 and 200,000 AU (0.8 and 3.2 ly). read more
