2005 TN53 (also written 2005 TN53) is a Neptune trojan discovered by Scott S. Sheppard and Chadwick A. Trujillo in 2005. It was the third such body to be discovered, and the first with a significant orbital inclination, which showed that the population as a whole is very dynamically excited. It has the same orbital period as Neptune and orbits at the L4 Lagrangian point about 60 degrees ahead of Neptune.
It has an inclination of 25 degrees.
With an absolute magnitude of 9.1, it is likely the smallest known Neptune trojan with a diameter in the range of 40 to 90 km.
It has been observed 23 times over 3 oppositions.
