 2005 TN74

It was initially suspected of being a Neptune trojan since the first observations gave it a semi-major axis of 30 AU and an orbital eccentricity of 0.16, but further observations showed it to have a semi-major axis of 42.7 AU, a perihelion of 32.1 AU, and an aphelion of 53.4 AU.With an absolute magnitude of 7.2, it has an expected diameter in the range of 85 to 240 km.
