TL66 is a scattered disc object like Eris. It has a perihelion of 35.029 AU, an aphelion of 130.774 AU, a semi-major axis of 85.33 AU and an eccentricity of 0.577.
In short, its orbit extends from that of Pluto to beyond that of Eris. It's inclination is 24.018 degrees, about a third greater than Pluto's, but not nearly as high as Eris's.
