1996 TO66 (center top) imaged by the NTT at La Silla in 1998. Other objects are elongated due to the 4-hour-exposure. The horizontal streak is from a geostationary satellite.
The eccentricity of 1996 TO66 varies between ca. 0.110 and 0.125 every 2 million years, with additional variations on the order of ± 0.01 on much shorter time scales. It is in an intermittent 19:11 resonance with Neptune. The resonance breaks every 2 million years when the eccentricity is highest and the orbit is closest to Neptune.[1]
