Like fossil fuels come from organic matter that grew because of the sun. Is there any form of energy on that cannot be traced back to the sun in some way?

It gets both slower and further away (to stay in orbit) every year, by like 2 cm IIRC.
If you could go back a couple billion years it would be huge in the sky. There was even a period, called the Jatulian, where you might not have asphyxiated in the early atmosphere. There wouldn’t be much else to look at, though, and just your skin germs would be futuristic enough to completely change the course of life on Earth, once they get into the environment.
So it will eventually escape it’s orbit?
Uhh, I actually don’t know the answer to that. Orbital mechanics is hard; see me being bamboozled elsewhere in the thread. At some point I’m guessing tidal forces from the sun would start having a major impact, since in reality they’re both in it’s gravitational well at the same time as they orbit each other. Usually that doesn’t make orbits more stable.
Also, the sun will go red giant in 4 or 5 billion years, and will eat Venus for sure. The Earth and Moon may well suffer the same fate, we’re kind of right on the projected edge.
