2007 NC7 (also written as 2007 NC7) is a Trans-Neptunian object discovered on September 6, 2007 by M.E. Schwamb, M.E. Brown and D.Rabinowitz .[4]

The object has a high eccentricity of 0.49. It comes within 17 AU of the Sun (inside the orbit of Uranus) and goes as far as 50 AU at aphelion (near the Kuiper cliff). It passed perihelion in September 1996.

For comparison, among the well established highly eccentric orbits formally classified as plutinos, the orbit of (15788) 1993 SB has an eccentricity of 0.318.

It has only been observed 26 times over 4 oppositions.[2]
