2005 TN53 (also written 2005 TN53) is a Neptune Trojan discovered by Scott S. Sheppard and Chadwick A. Trujillo in 2005. Only five others are known: 2001 QR322, 2004 UP10, 2005 TO74, 2006 RJ103 and 2007 VL305. They have the same orbital period as Neptune and orbit at the L4 Lagrangian point about 60 degrees ahead of Neptune.[1]
It has an inclination of 25 degrees.[1][2]
With an absolute magnitude of 9.1,[2] 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.[2]
