(532037) 2013 FY27 (provisional designation 2013 FY27) is a trans-Neptunian object and binary system that belongs to the scattered disc (like Eris).

Using the Atacama Large Millimeter Array and Magellan Telescopes, its albedo was found to be 0.17, and its colour to be moderately red.

The physical processes that lead to a lack of such moderately red TNOs larger than 800 kilometres (500 mi) are not yet well understood.

[4] Brown estimated, prior to the discovery of its satellite, that 2013 FY27 was very likely to be a dwarf planet, due to its large size.

[12] Using Hubble Space Telescope observations taken in January 2018, Scott Sheppard found a satellite around 2013 FY27, that was 0.17 arcseconds away and 3.0±0.2 mag fainter than its primary.
