Our aim is to identify and classify mean-motion resonances ( MMRs ) for the coplanar circular restricted three-body problem ( CR3BP ) for mass ratios between 0.10 and 0.50 . Our methods include the maximum Lyapunov exponent , which is used as an indicator for the location of the resonances , the Fast Fourier Transform ( FFT ) used for determining what kind of resonances are present , and the inspection of the orbital elements to classify the periodicity . We show that the 2:1 resonance occurs the most frequently . Among other resonances , the 3:1 resonance is the second most common , and furthermore both 3:2 and 5:3 resonances occur more often than the 4:1 resonance . Moreover , the resonances in the coplanar CR3BP are classified based on the behaviour of the orbits . We show that orbital stability is ensured for high values of resonance ( i.e. , high ratios ) where only a single resonance is present . The resonances attained are consistent with the previously established resonances for the Solar System , i.e. , specifically , in regards to the asteroid belt . Previous work employed digital filtering and Lyapunov characteristic exponents to determine stochasticity of the eccentricity , which is found to be consistent with our usage of Lyapunov exponents as an alternate approach based on varying the mass ratio instead of the eccentricity . Our results are expected to be of principal interest to future studies , including augmentations to observed or proposed resonances , of extra-solar planets in binary stellar systems .
