2010 GB174 is a detached object. It never gets closer than 48.5 AU from the Sun (about the outer edge of the Kuiper belt). Its large eccentricity strongly suggests that it was gravitationally scattered onto its current orbit. It is, like all detached objects, outside of the current influence of Neptune, so how it got its current orbit cannot yet be explained.

It reached perihelion (closest approach to the Sun) around 1952[1] and is currently 69.8 AU from the Sun.[4] In September 2014, it will move beyond 70 AU from the Sun.

It is possibly a dwarf planet.[2]
