C/2014 OG392 (PanSTARRS) is a

billion km) from the Sun and had an apparent magnitude of 21.[3] The comet was relatively easier to detect at this distance because the nucleus is estimated to be 20 km in diameter.[2]

activity likely produced by carbon dioxide (CO2) and/or ammonia (NH3) sublimation (off-gassing).[2]

Clones of the orbit of C/2014 OG392 estimate a dynamic lifetime (amount of time in the current orbit) of 13 thousand to a million years.[2]

Perihelion (closest approach to the Sun) takes place not far from Saturn's orbit with a Saturn minimum orbit intersection distance of 0.9 AU (130 million km);[4] for example on 29 September 2231 at about 0.934 AU (139.7 million km) ±1 million km from Saturn.[5]

C/2014 OG392 will come to

perihelion in late July 1979 and will next come to perihelion on 29 November 2021.[1]
