Table 1
Number of asteroids in the leading and trailing resonance islands and their ratios (L/T) in some major 1:N resonances.
| Resonance | Leading | Trailing | Symmetric | L/T |
|---|---|---|---|---|
| Jup. 1:1 | 8282 | 4457 | N.A. | 1.86 |
| Nep. 1:1 | 27 | 4 | 1 | 6.75 |
| Nep. 1:2 | 32.4 | 9.8 | 17.0 | 3.31 |
| Nep. 1:3 | 4.6 | 0.6 | 8.1 | 7.67 |
| Nep. 1:4 | 3.8 | 0.4 | 0.8 | 9.50 |
Notes. The data of 1:1 resonance with Jupiter or Neptune are from the IAU MPC, while other values were calculated based on our simulations, with the initial orbital elements obtained from the Asteroids-Dynamic Site. For the 1:N (except for 1:1) MMRs hosting only a small number of detected objects, clone orbits were generated and their orbital statuses were used to obtain the statistical numbers in this table (see text).
