On the Possibility of a Resonance Capture of the Asteroid Toro by the Earth
Among the very few tabulated asteroids with perihelion inside the Earth’s orbit (Apollo asteroids) some have periods nearly commensurable with the Earth’s. The perturbed orbit of one of these, 1685 Toro, has been integrated over 1200 years. The results show that Toro is at present captured in resonance with the Earth and that also Venus has a drastic influence on the orbital elements.
