At what point are orbital resonances no longer "ordered" but "chaotic?"
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 ...

Do Astronomers really never call Lagrangian points "libration points"?
In this answer to Who called the Lagrangian points as “Libration” points and and why was the terminology “Libration” used? I described my feeling that Lagrangian points were also sometimes called &...

How often does the configuration of the Trappist-1 system repeat
My question is simply how long it takes for the 7 known planets in Trappist-1 to be in the same configuration in relation to their host star, and to each-other. Those seven planets are in a 2:3:4:6:9:...

Why does the exoplanetary system TOI-178 challenges current theories of planet formation?
I am excited reading the news about ESA's latest exoplanet discovery using CHEOPS. The system TOI-178 consists of (at least?) five planets, following a 18:9:6:4:3 pattern. In the press release, the ...

Explanation about the resonance, mean motion resonance and libration
I am studying for a project the dynamics of multi-planetary system in resonance. I have two questions about this domain.
In many articles they speak about 'mean motion resonance', what is the ...

Why wasn't CHEOPS data taken during passage through the South Atlantic Anomaly downlinked in this case, resulting in gaps in photometry?
Section 4.1.2. CHEOPS in Six transiting planets and a chain of Laplace resonances in TOI-178 says
Due to the low-Earth orbit of CHEOPS, the spacecraft-target line of sight was interrupted by Earth ...

Can a celestial body be tidally locked to multiple other bodies at the same time?
Could a planet be tidally locked to both the star it is orbiting and a moon orbiting the planet at the same time? I feel like it wouldn't be possible, because I think it would cause the moon to crash ...

How to choose initial state vectors for a resonant orbit numerical simulation?
How do higher numbers affect orbital resonance? is a really interesting question, and I thought I would try to do a simple numerical simulation of various resonance ratios to see if some are ...

If all the Trappist-1 planets are tidally locked, which ones may have temperate zones?
Since all the Trappist-1 planets have circular orbits, it is entirely likely that all them are tidally locked.
If so, which ones of the planets may have temperate zones either on the bright or dark ...

What exactly is the relationship between the orbits of Neptune's moons Naiad and Thalassa?
Scitechdaily's Wild Orbits of Neptune Moons a ‘Dance of Avoidance’ [Video] links to the YouTube video Neptune Moon Dance (Naiad and Thalassa) and says:
In this perpetual choreography, Naiad swirls ...

Just how resonant is the "resonant sextuplet of sub-Neptunes transiting the bright star HD 110067"?
The November 29, 2023 arXiv preprint A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067 constructs a resonant chain of orbital periods based on mean motion resonances (MMRs) and ...

Does Trappist-1 have a Periodic Configuration? [duplicate]
Trappist-1's planetary system is notable for having 7 planets in a resonance chain. I would think, since all the planets are in resonance, the system would have a repeating configuration that could be ...
