The diameter of the largest of the outdoor facilities is 800 kilometers.
Celestial mechanics from the United States opened several large TRANS-Neptunian objects (i.e., located beyond the orbit of Neptune) and studied their interaction with the gas giant.
Devoted to the study of a Preprint published on the website arXiv.org.
Scientists gave details of the public using the Subaru Observatory and Cerro-Tololo eight TRANS-Neptunian objects: 2014 FZ71, 2015 FJ345, 2004 XR190, 2013 FQ28, 2015 KH162, GP50 2015, 2014 and 2012 FC69 FH84.
The largest of them is 2015 KH162. The diameter of the object observed 41 times equal to 800 kilometers. Length of the major semiaxis of its orbit is equal 61,9 astronomical units, the eccentricity (the parameter of elongation of the orbit) is 0.33.
Period 2015 KH162 and Neptune around the Sun are related as 3:1. Objects FZ71 2014 and 2015 FJ345 are the third and fourth largest known perihelion after the dwarf planets of Sedna and 2012 VP113, but their orbits are not the same eccentric. Trajectory FZ71 2014 and 2015 FJ345 probably formed as a result of the Kozai mechanism-Lidova.
