    2013 AZ60 is a small Solar System body (extended centaur)[2] from the scattered disk or inner Oort cloud. 2013 AZ60 has the 5th-largest semi-major axis of a minor planet not detected outgassing like a comet[5] (2013 BL76, 2005 VX3 and 2012 DR30 have a larger semi-major axis).

    2013 AZ60 came to perihelion in November 2014 at a distance of 7.9 AU from the Sun (inside of the orbit of Saturn). With an absolute magnitude (H) of 10.2,[2] 2013 AZ60 has an estimated diameter of 40 km.[4] Comet Hale–Bopp, which is roughly the same size, was not discovered until it was 7.2 AU from the Sun and had started outgassing CO. 2013 AZ60 may be discovered to be cometary as it comes to perihelion.

    After leaving the planetary region of the Solar System, 2013 AZ60 will have a barycentric aphelion of 828 AU with an orbital period of 8500 years.
