2013 FY27, also written 2013 FY27, is a trans-Neptunian object[3] that belongs to the scattered disc (like Eris).[6] Its discovery was announced on 31 March 2014.[1] It has an absolute magnitude (H) of 3.0,[3] which makes it very likely to be a dwarf planet.[4] Assuming an albedo of 0.15, it would be approximately 850 kilometres (530 mi) in diameter.[5] It is the ninth-intrinsically-brightest known trans-Neptunian object,[7] and is the largest unnumbered minor planet as of October 2015.
2013 FY27 will come to perihelion around 2198,[lower-alpha 3] at a distance of about 36 AU.[3] It is currently near aphelion, 80 AU from the Sun, and, as a result, it has an apparent magnitude of 22.[1] Its orbit has a significant inclination of 33°.[3]
First observed on 17 March 2013, it has an observation arc of about one year.[3] 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.
