that probably happened a few times as well we "stolen" planets or mass from other star systems in the same baby nursery as our sun

there is also likely a planet that passed through and yanked away a lot of debris, most of the simulations for tilt etc. don't work without the mystery missing planet

I could watch PBS Space Time all day for that kind of stuff, often do letting it play in the background on repeat, so much better than the news

Another interesting concept here is that the solar system is a second generation(minimum) system, too much iron+ for a first generation system. So the first generation star had explode to form all the heavy metals. Where is the original stellar remnant? Is there a Black hole or neutron star or whatever it is called if it can't even make it to neutron star levels in roughly the same galactic orbit as our sun?.

A good follow up question that nobody knows the answer to is "how much iron is in the sun?" The problem as I understand it is we can only directly see the very outer layer where there is no iron, so the standard answer is statistically none, only fractional percentages. But based on the distribution of elements in the solar system I sort of expect a sizable iron core.
