About: C/2014 OG392 (PanSTARRS)

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

C/2014 OG392 (PanSTARRS) is a comet discovered as a centaur on 28 July 2014 when it was 11.5 AU (1.72 billion km) from the Sun and had an apparent magnitude of 21. The comet was relatively easier to detect at this distance because the nucleus is estimated to be 20 km in diameter. DECam images from 2017 of the comet at 10.6 AU (1.59 billion km) from the Sun showed activity likely produced by carbon dioxide (CO2) and/or ammonia (NH3) sublimation (off-gassing). 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.

dbo:abstract
  • C/2014 OG392 (PanSTARRS) is a comet discovered as a centaur on 28 July 2014 when it was 11.5 AU (1.72 billion km) from the Sun and had an apparent magnitude of 21. The comet was relatively easier to detect at this distance because the nucleus is estimated to be 20 km in diameter. DECam images from 2017 of the comet at 10.6 AU (1.59 billion km) from the Sun showed activity likely produced by carbon dioxide (CO2) and/or ammonia (NH3) sublimation (off-gassing). 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. 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); for example on 29 September 2231 at about 0.934 AU (139.7 million km) ±1 million km from Saturn. C/2014 OG392 will come to opposition on 1 November 2021 in the constellation of Cetus when it will have a solar elongation of 170 degrees. Numerical integration shows the comet last came to perihelion in late July 1979 and will next come to perihelion on 29 November 2021. (en)
