2013 FZ27, also written 2013 FZ27, is a trans-Neptunian object that, as of 2014, is located near the edge of the Kuiper belt. Its discovery was announced on 2 April 2014. It has an absolute magnitude (H) of 4.0, which makes it likely to be a dwarf planet. Assuming an albedo of 0.15, it would be approximately 500 kilometres (310 mi) in diameter.
2013 FZ27 will come to perihelion in September 2090, at a distance of 37.98AU. As of 2014, it is 49 AU from the Sun and has an apparent magnitude of 21.1.
First detected on 16 March 2013, it had an observation arc of about one year when announced. It came to opposition in late February 2014. Four precovery images, by Pan-STARRS from 21 February 2013, were quickly located. Eight more precovery images, by Pan-STARRS from January and February 2011, have been located, extending the observation arc to 1151 days. Later, three precovery observations by the Sloan Digital Sky Survey in February 2001 were also found, giving it a well-defined 13-year (4782 day) observation arc.
The sednoid 2012 VP113 and the scattered-disc object 2013 FY27 were discovered by the same survey as 2013 FZ27 and were announced a few days before.
