Orbit
Now 2013 FY 27 is at a distance of 80 a. e. from the sun. In aphelion, the object is removed at 82.6 a. e. from the sun. In 2198, the object will undergo perihelion (36 AU). The inclination of the orbit is 33 Β°.
For 2014 2012 VP113 was at a distance of 83 a. e. from the sun. V774104 , opened in 2015, was located at a distance of about 103 a. e. from the Sun, Eris as of 2012 was at 96.5 a. e. from the Sun, 2014 UZ224 as of 2016 was at 91.6 a. e. from the sun.
Physical Characteristics
Without special studies, the albedo value of 2013 FY 27 can only be assumed. If we assume that it lies in the range 0.05-0.25, then the diameter of the object can be in the range from 670 to 1,500 km. According to M. Brown, with an albedo of 15% and a magnitude of 3.3, the diameter of 2013 FY 27 will be 760 km [1] .
