38628 Huya (pronounced /huːˈjɑː/, original provisional designation: 2000 EB173) is a trans-Neptunian object (TNO). It was discovered in March 2000 by Ignacio Ferrin and announced on 24 October 2000. It is classified as a plutino with a 2:3 mean motion resonance with Neptune. It was assigned the name Huya, after Juyá, the Wayuu rain god, in August 2003 by the International Astronomical Union (IAU).
At the time of its discovery, Huya was the biggest and brightest TNO yet found. It was found using data collected by at the CIDA Observatory in Venezuela. It is estimated to be 480 km in diameter.
[edit] Surface
The object has a red-sloped reflectance spectrum, suggesting a surface rich in organic material such as tholins.[4]
Given the long orbit that TNOs have around the sun, Huya comes to opposition in early May of each year at an apparent magnitude of 19.3.
