is a trans-Neptunian object (TNO) with an absolute magnitude of 4.4.
Orbit
is classified as scattered-extended by the Deep Ecliptic Survey (DES), because its orbit appears to be beyond significant gravitational interactions with Neptune's current orbit. However, if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity. The aphelion of lies at 104 AU.
Simulations by Emelʹyanenko and Kiseleva in 2007 showed that appears to have less than a 1% chance of being in a 4:1 resonance with Neptune.
It has been observed 202 times over seven oppositions. It came to perihelion in January 2017. There are precovery observations dating back to November 2001.
Physical properties + History of size estimates for YearDiameter (km)References201020122013 In 2010, thermal flux from in the far-infrared was measured by the Herschel Space Telescope. Initially, its size was estimated to lie within a range from 335 to 410 km. Upon further analysis, its size was estimated to be around .
In the visible light, has a moderately red spectral slope.
The TNO was found in 2009 to have a rotation period of 12.68 ±3 hours, a common value for trans-Neptunian objects of its size. Similarly sized has a rotation period of 11.7 ± 3 hours.
