Jupiter does not orbit the sun

[Polymath257]

That is exactly why I chose the larges value that I could find. Frankly it is beyond me how they define an "edge" at roughlty 1 and 1/3 of a light year out. If one uses Pluto the answer is obvivus. But if one is willing to go to exterme and unreasonable distances then dark matter may become a noticable fracition of th emass of the Solar System. mass.

Well, we would want to include at least the Kuiper beelt objects and probably the Oort cloud. That takes things considerably beyond Pluto.

I agree. The question was about dark matter and if one assumes a fairly constant distribution throughout the galaxy even then dark matter would be a small percentage of the total. But how much regular matter is thought be in those two volumes?

Is that right? Odyssey was about turning Jupiter into a new sun? Oh my failing memory ...

2010 had the new sun development

Clarke also wrote the template to that one.

In reality Jupiter is not massive enough to sustain fusion, even if it could be compressed to the ignition point.

I think it is relevant to ask about the time required for extinction in such a case. if ignition happens, how long does it take before fusion stops again? if it is a few million years, that might be enough to accomplish the goals of the beings in the 2001 series.

Depends on how and if the pressure is maintained. Assuming there is no containment, the reaction would stop basically immediately. The radiation pressure would expand the core, thereby cooling it below fusion temperature.

That makes perfect sense, yes.

Thanks for that.
