Google "sun percentage mass solar system" and the highlighted answer is "By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent."

Please don't just disagree when you don't know what you are talking about.

I think you've misinterpreted my post. The "No" was in response to this:

> That always confused me. We have an Oort cloud, whose members we cannot resolve very well/at all. Why do we assume only our star has such a thing? If all stars did, that isn't enough mass to explain dark matter?

No, that isn't enough mass to explain dark matter, since it's only 0.1% to 0.2% of the mass of the solar system.

The text I quoted was in complete agreement with what you and others have posted. I was pointing out that the questioner's point had already been answered.

Ok, that's just a really confusing way of communicating, nobody is going to puzzle that out when the obvious way of looking at your response is disagreement with the grandparent.
