2005 TO74 (also written2005 TO74) is a possible Trojanasteroid of Neptune which was discovered by Scott S. Sheppard and Chadwick A. Trujillo in 2005. Only two others are known: 2001 QR322 and 2004 UP10. They have the same orbital period as Neptune and orbit at the L4Lagrangian point about 60 degrees ahead of Neptune. In ancient times, only the Sun and Moon, a few hundred stars and the most easily visible planets had names. ...

Trujillo (born November 22, 1973) is a postdoctoral scholar at Caltech researching the Edgeworth-Kuiper belt and the outer solar system. ... 2001 QR322 (also written 2001 QR322) is an asteroid discovered in 2001 that is one of the two currently known Trojan asteroid of Neptune (the other is 2004 UP10). ... 2004 UP10 is a Trojan asteroid of Neptune, and one of only two known. ... Adjective Neptunian Atmospheric characteristics Surface pressure ≫100 MPa Hydrogen - H2 80% ±3. ... The Lagrangian points (IPA: ; also Lagrange point, L-point, or libration point), are the five positions in space where a small object can be stationary with respect to two larger objects (such as a satellite with respect to the Earth and Moon). ...
One of them, 2005 TN53, is unusual in that its orbit is tilted 25° relative to the plane of the solar system.
The known NeptuneTrojans are estimated to have diameters of 60 to 140 km.
From a statistical analysis based on the 25° tilt of 2005 TN53's orbit, researchers have inferred that Neptune may have between five and 20 times more of these large objects than Jupiter does.
