I noticed something looking at the Longitude of the Ascending node of various planets.

  • Mercury: 48.331°
  • Venus: 76.680°
  • Mars: 49.57854°
  • Jupiter 100.464°
  • Saturn: 113.665°
  • Uranus: 74.006°
  • Neptune: 131.783°

I noticed that the average Longitude of the Ascending node increases greatly after after the frost line, with Jupiter. Is there any physical law that makes them increase like this as they get further from the sun, or increase in semi-major axis? Or is it just coincidence? Uranus having less than Venus makes it seem like it may just be coincidence, but it is still above Mercury and Mars, so the idea of the average increasing still holds.

    $\begingroup$ The orbital nodes precess, so these values aren't fixed, so I'd guess "co-incidence", as in 100000 years of so, the values will be mixed up. It's also notable that al these values are less than 180, again I think coincidence. $\endgroup$

  • $\begingroup$ Thank you, I assumed that it was coincidence due to Uranus, but just wanted to make sure there wasn't something I was missing. $\endgroup$ Dec 30, 2023 at 20:49
