2013 FZ27, also written 2013 FZ27, is a trans-Neptunian object that, as of 2014, is located near the edge of the Kuiper belt.[3] Its discovery was announced on 2 April 2014.[1] It has an absolute magnitude (H) of 4.0,[3] 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.[4]
2013 FZ27 will come to perihelion in September 2090,[lower-alpha 3] at a distance of 37.98AU.[3] As of 2014, it is 49 AU from the Sun and has an apparent magnitude of 21.1.[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.[2] Eight more precovery images, by Pan-STARRS from January and February 2011, have been located, extending the observation arc to 1151 days.[2] 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.
