The group took the orbital resonance
frequencies of Saturn's moons and the dust particles in its rings and (http://www.
A property that is associated with an orbital resonance
, or a mean-motion orbital resonance
, in particular.
Our best guess is that Saturn had a similar collection of moons before, but their orbits were disturbed by a special kind of orbital resonance
involving Saturn's motion around the Sun.
The only way they can 'get along' and become stable is if they enter an orbital resonance
Dynamicists already suspect that the new find might be in an orbital resonance
In QCM the predicted period ratios for the orbital resonance
conditions in the last column of Table 1 are calculated from the m values using
The six inner planets stay in place due to orbital resonance
, which means they all have a slight gravitational pull on one another as they orbit the star together.
Astronomers had found that the Cassini Division maintains a 1:2 orbital resonance
with Saturn's innermost known moon, Mimas.
Their stability can to some extent be explained by the phenomenon of orbital resonance
, but this explanation is certainly not enough.
In QCM the orbital resonance
condition is given by the period ratio given in the last column calculated from
It's quite elongated, inclined to the ecliptic plane that contains the orbits of the eight planets, and in a 2:3 orbital resonance
with Neptune, going around the Sun twice every three Neptune years.
Apparently they are locked in a 2:1 orbital resonance
but are strongly "librating" (oscillating) back and forth around that perfect ratio in a 4-year cycle.
