2013 FY27, also written 2013 FY27, is a trans-Neptunian object that belongs to the scattered disc (like Eris). Its discovery was announced on 31 March 2014. It has an absolute magnitude (H) of 3.0, which makes it very likely to be a dwarf planet. Assuming an albedo of 0.15, it would be approximately 850 kilometres (530 mi) in diameter. It is the ninth-intrinsically-brightest known trans-Neptunian object, and is the largest unnumbered minor planet as of October 2015.
2013 FY27 will come to perihelion around 2198, at a distance of about 36 AU. It is currently near aphelion, 80 AU from the Sun, and, as a result, it has an apparent magnitude of 22. Its orbit has a significant inclination of 33°.
First observed on 17 March 2013, it has an observation arc of about one year. It came to opposition in early March 2014.
The sednoid 2012 VP113 and the scattered-disc object 2013 FZ27 were discovered by the same survey as 2013 FY27 and were announced within about a week of one another.
