The orbits of Saturn and Jupiter continue so slowly grow more eccentric and inclined. It looks like Neptune is now in an orbit that won't take it more than a couple of AU from the Rogue.ģ. It appears that they happened in the last 7 orbits because Neptune's orbital inclination has jumped from just under 15 degrees to 19.4 degrees and the eccentricity has jumped to 0.27. Uranus' orbit remains unchanged but I noticed last night that there was the possibility of some fairly close encounters between Neptune and the Rogue. In fact Mars' orbit is already starting to show fairly rapid change with the eccentricity and inclination both increasing noticeably every time I check the program.Ģ. This is setting it up orbits where it could pass as close as 0.3 AU to Mars. The inclination is down to 125 degrees and the eccentricity is up to 0.92. The orbit of the Rogue Planet continues to evolve. Note that this is probably the last update where the inner solar system is not disrupted.ġ. The simulation is now at 16941 simulated years, 169+/- 5 orbits of the rogue planet. The initial orbit had a perihelion of about 2.8 AU, and aphelion of about 40 AU (eccentricity of 0.90), and a period of 100 years. This update is to our solar system with a rogue Jupiter size planet in an initial 135 degree inclined orbit (or 45 degree retrograde depending on how you want to think about it) with the semi-major axis tilted 30 degrees to the ecliptic. Since it looks like some people are reading this and somebody is looking at the simulations, I'll keep doing it. Uranus continues to get kicked onto longer and longer orbits and now has an aphelion outside the Kuiper Belt included in this simulation. Uranus and Neptune appear to be interacting and both are inclined about 15 degrees now. 4) and Jupiter has a perihelion under 4 AU.ĥ. While the orbits of Jupiter and Saturn haven't inclined too much, but are now quite eccentric (about. It's inclination is decreasing (started at 135 but has been slowly decreasing) and the orbit is more eccentric (perihelion is now well under 2 AU).Ĥ. The orbit of the Rogue Jupiter Sized Planet has evolved somewhat. The asteroid belt is barely recognizable.ģ. The orbits have inclined a bit, but the eccentricities are still very low. The inner solar system is still fairly stable. Interesting things to note since the last update:ġ. It is up to 14514 simulated years (145 +/- 5 orbits of the rogue planet) and seems to be evolving more quickly now. So, my question is, is anybody else using US this way? If so, what have you found to be interesting systems to investigate? If anybody is interested, I'm happy to post either/both of my systems to the board.Īnother update for my Rogue Jupiter simulation. I suspect that this is largely due to the long orbit (~100 years) and the fact that the real Jupiter is stabilizing the system. The second is evolving much more slowly (although I can definitely see effects). The first system obviously evolves MUCH faster because the "real" Jupiter isn't there to stabilize the inner solar system and it is on about a 5 year orbit. I find it interesting to see how the systems evolve with time. I had a bit over 4100 years of simulated times on it as of this morning. Took our solar system and put an extra captured Jupiter mass rogue planet on a highly elliptical (2.2 - 41 au) highly inclined (135 degrees (or 45 degree retrograde) with the axis tilted at 30 degrees) orbit and then let it run at 7 d/s. I have about 9000 years of simulated time on it. Our solar system where I took Jupiter, cut the speed of the starting orbit in half and inclined it by 30 degrees to the ecliptic, and then let it run at 7 d/s. The two I have the most time on so far are: Although I have been building systems and have played with collisions, I'm having the most fun putting together "what if" situations and letting them run to see how a system evolves. It seems like everybody I see is either interested in building stable systems or interesting collisions. I've been going through the posts on this board and especially like some of the systems that people have created.
