The asteroid 1685 Toro has its perihelion inside the Earth's orbit and a period which is 8/5 of that of the Earth. A calculation of Toro's orbit covering 200 years shows that this asteroid at present is captured in resonance with the Earth. The capture is due to the gravitational interaction at close encounters between the bodies.
