1999 OJ4 UAS: Mauna Kea Rock (Common Name: Mauna Rock )

1999 OJ4 is a trans-Neptunian object and binary system from the classical Kuiper belt, located in the outermost region of the Solar System. The bright cubewano belongs to the cold population and measures approximately 75 kilometers in diameter. It was first observed at Mauna Kea Observatory on 18 July 1999. Discovered in 2005, its minor-planet moon is just 3 kilometers smaller than it's primary and has an orbital period of 84 hours.

Orbit and Relationship with the Kuiper Belt
1999 OJ4 orbit characterizes it as a classical Kuiper Belt object or cubewano. Due to its nearly circular orbit and low inclination, it is also in the "cold" population of cubewanos. As a result, it is likely reddish in color.

Moon
UAS: Hubble13 (Common Name: Hubble 13)

1999 OJ4 has one moon, S/2005 (1999 OJ4) 1. This moon was discovered by the Hubble Space Telescope on 5 October 2013. It orbits 3,267 kilometers away from 1999 OJ4, completing one orbit every 84.115 days. At 72 km, it is nearly the same size as 1999 OJ4. From the surface of 1999 OJ4, S/2005 (1999 OJ4) 1 would have an apparent diameter of roughly 8.11°, over fourteen times the apparent size of the Sun from Earth.
