Our numerical integrations (over a time span of a few Myr) have shown that: (i) the linear secular resonances with both the inner and the outer planets may play an important role in the dynamical evolution of NEAs; (ii) the apsidal secular resonance with Mars cou

Since 1975 we have also been aware of an apparently massive meteoroidal swarm in probable 7:2 mean motion resonance with Jupiter, seemingly at the heart of the Taurid Complex and connecting therefore with the near-ecliptic system through the so-called ?to

We confirm the proposition made by Ferraz-Mello and collaborators that the great inequality generates secondary resonances which are likely to produce the slow diffusion observed in numerical investigations. We identify, in the restricted three body problem, the freque

For both regular and chaotic orbits we try to associate the motion to the underlying resonances network. For it we co

We have made a systematic search of encounter chances (encounter duration and velocity) with the major meteor showers taken from the Kronk’s catalog (1988) for some mission target asteroids and Mars. It is argued that dust clouds much enhanced by stream impacts are on

Of these three factors, the collision with minor body is the most serious for continuation of civilization of mankind, because, the civilization will be collapsed completely by the collision with a some size minor body.

Yinan Fu,Xiaolong Zheng,Peilun Du,Liang LiuThe lack of asteroids in the 2/1-resonance is explained by the global stochasticity of the solutions in the Sun-Jupiter-Saturn-asteroid model. The explanation is based on data obtained with Laskar’s frequency map analysis and on simulations showing the decisive influence of Jupiter’s orbit perturbations related to the “Great Inequality”.
