The title essentially explains the question. I was wondering if the galactic tide could play a role in raising perihelia of extreme trans-Neptunian objects (i.e. Sedna) versus the effect of a hypothet …

The Sun orbits approximately 26,000 light years away from the galactic center. Are there any other known orbital parameters relative to the galactic plane for the Sun and other stars up to some distan …

Continuing, using the formula for the incircle and excircle of bicentric, regular polygons, where the incircle is the Earth and the excircle is the satellite network orbit, (see the Wikipedia article), … the orbital radius is equal to $R=\frac{6371}{\cos{\frac{\pi}{n}}} - 6371$, where $n$ is the number of satellites in orbit. …

Previously, I asked At what point are orbital resonances no longer "ordered" but "chaotic?", and received an answer from @CarlWitthoft: Perhaps if the calculated fraction had an irrational num or den …

Orbital resonances are typically in small valued integer ratios, like 2:1, 3:2, or 4:7. However, there are some resonances whose ratios have large reduced values, including the 73:69 Naiad:Thalassa re …

orbiting at the edge of the Hill sphere may seem like they are stable, but long-term stability tends to indicate that objects orbiting at half of the sphere are stable, meaning that a planet could stably orbit …

Because most comets have inclinations different than that of the ecliptic plane and do not intersect the orbit of a planet, with the famous exception of Comet Bowell in a close swingby of Jupiter, with … As a result, why are such small perturbations of planets several AU away enough to take a comet from a closed to an open orbit? How close to escape velocity are most Oort-cloud comets? …

When talking about celestial bodies orbiting the sun with a decently circular orbit or small aphelion, the heliocentric orbital parameters are almost identical to the barycentric parameters. …

I was reading the Wikipedia article about orbital resonance and noticed that Laplace resonances forbid triple conjunctions. This seems to be supported by the Io-Europa-Ganymede system and the Nyx-Styx …

The Wikipedia article about Kepler's third law includes a nice table about the ratio between $a^3$ and $T^2$. However, for Mars, Jupiter, Saturn, Uranus, and Neptune, the ratio $\frac{a^3}{T^2}$ in $1 …

Trojans typically intersect the orbit of its relative body. Typically, these are stable in the long-term, especially when the planet is massive. … Are such orbits which intersect the orbit of a massive body within the distance of its Hill sphere ever stable? If so, when? …

Comets' orbits often change during perihelion passage due to the outgassing of volatiles. So I am wondering, how much change in velocity is applied each perihelion pass? What does this depend on?

I'm conducting research on solar system dynamics, and found a list of asteroids in retrograde orbits, but none about the ones orbiting perpendicular to the ecliptic plane. Are there any detailed lists …

After a minute of running, the orbit began noticeably expanding: Why is it happening, and is this natural? The source code is based on https://github.com/lemmingapex/N-bodyGravitySimulation. …

I can convert that to $(x,y,z)$ coordinates, but is there any defined orbit for Luhman 16 AB? I've tried looking it up on Arxiv, but the results do not give any information regarding their orbit. …
