There is a near-resonance between the precession of Saturn's rotational axis and that of Neptune's orbital axis (both of which have periods of about 1.87 million years), which has been identified as the likely source of Saturn's large axial tilt (26.7°).
The most prominent Kirkwood gaps are located at mean orbital radii of: [4] 1.780 AU (5:1 resonance); 2.065 AU (4:1 resonance) 2.502 AU (3:1 resonance), home to the Alinda group of asteroids
The researchers determined that the six planets were in a rare condition called orbital resonance, with their synchronized orbits around the star apparently unchanged since they formed about 4 ...
Another common form of resonance in the Solar System is spin–orbit resonance, where the rotation period (the time it takes the planet or moon to rotate once about its axis) has a simple numerical relationship with its orbital period. An example is the Moon, which is in a 1:1 spin–orbit resonance that keeps its far side away from
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.
Enceladus is currently in a 2:1 mean-motion orbital resonance with Dione, completing two orbits around Saturn for every one orbit completed by Dione. [6] This resonance maintains Enceladus's orbital eccentricity (0.0047), which is known as a forced eccentricity. This non-zero eccentricity results in tidal deformation of Enceladus.
The three planets are in an orbital resonance.

The puffier planets were more likely to be at least close to resonance. Later expanding their sample size to 133, they found the same thing. Subsequent computer simulated systems told the same ...
