compared to Huya, the satellite is expected to have slowed Huya's rotation such that both components become mutually tidally locked, although several photometric observations of Huya indicate a rotation period of several hours, suggesting that Huya may not be tidally locked to its satellite. If Huya is not tidally locked to its satellite, this implies that the satellite could have a very low density of around , which would result in a longer time for both components to become mutually tidally locked. The orbit of the satellite is poorly known due to the small number of resolved observations of Huya's satellite. Consequently, a definitive mass and density estimate for Huya cannot be derived from the satellite's orbit. Based on archival Hubble images of Huya taken in 2002, the satellite's angular separation distance from Huya is approximately 60 to 80 milliarcseconds, corresponding to an approximate distance of . Astrometry of the satellite's changing position around Huya from two Hubble images taken one day apart in 2002 indicates a rough orbital period estimate of about 3.2 days.
