38628 Huya (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. It was assigned the name Huya, after a South American 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. A plutino with a 3:2 resonant orbit with Neptune, the object was found using data collected by a 1-meter telescope at the CIDA Observatory in Venezuela. It was estimated to have a diameter of 597 km, about one-fourth the size of Pluto. As such, it was commonly referred to as a large asteroid rather than a potential planet.
The object appears to be dark red, suggesting it is covered with ancient organic chemistry.
