2005 TN53 (also written 2005 TN53) is a Neptune trojan discovered by Scott S. Sheppard and Chadwick A. Trujillo in 2005.[4] 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.[5]

It has an inclination of 25 degrees.[1][5]

With an absolute magnitude of 9.1,[1] it is likely the smallest known Neptune trojan with a diameter in the range of 40 to 90 km.[3]

It has been observed 23 times over 3 oppositions.[1]
