bright glare. The satellite measures roughly in diameter, based on a near-infrared magnitude difference of 10.5. The satellite has been identified in later VLT images from February 2016 and July-August 2019. With a semi-major axis of and an orbital period of , is the innermost companion of the Elektra system. In contrast to the two outer satellites, the orbit of is remarkably eccentric and inclined; it has a high eccentricity of 0.33 and an inclination about 38° with respect to Elektra's spin axis (129° with respect to the celestial equator). The satellite's close proximity to Elektra makes its orbit subject to perturbations by shape-induced irregularities in Elektra's gravitational field (see geopotential model), which may account for most of the uncertainties in Keplerian orbit solutions for .
