(574372) 2010 JO179

(574372) 2010 JO179 (provisional designation 2010 JO179) is a large, high-order resonant trans-Neptunian object in the outermost regions of the Solar System, approximately 700 kilometers (430 miles) in diameter.

[6] The Minor Planet Center credits the object's first official observation on 10 May 2010 to Pan-STARRS (F51) at Haleakala Observatory, Hawaii, United States.

[6] There are 4 February 1951 precovery images from the Palomar Observatory Sky Survey, extending the observation arc by approximately 60 years.

[1] The precovery images are from the same year the object came to perihelion (closest approach to the Sun).

[1] Photometric observations of 2010 JO179 gave a monomodal lightcurve with slow rotation period of 30.6 hours, suggesting a rather spherical shape with significant albedo patchiness.
