15 August 2003, by a team of astronomers led by W. J. Merline using the Keck II telescope at the Mauna Kea Observatory in Hawaii. The discovery images showed that the satellite had an apparent magnitude difference of 8.5 in the near-infrared K-band. The team confirmed the existence of the satellite after reobserving it with the Keck II telescope on 17 August 2003. The discovery was announced on that same day and the satellite was given the provisional designation . orbits from Elektra with a period of 5.3 days. Its orbit has a moderate eccentricity of 0.08 and an inclination of 160° with respect to the celestial equator. Preliminary simulations of the Elektra system show that 's semi-major axis oscillates less than over 20 years. Near-infrared observations from December 2014 show that along with display a similar spectrum to Elektra, supporting the hypothesis that they are fragments from a disruptive collision. S/2014 (130) 1 is the second satellite of Elektra by distance and order of discovery. It was discovered on 6 December 2014, by a team of astronomers led by B. Yang using the SPHERE adaptive optics system on the Very Large Telescope's Melipal (UT3) telescope at Cerro Paranal, Chile. Discovery observations showed that the satellite had a near-infrared magnitude difference of 10, corresponding to a diameter of about if it has the same albedo as the primary. The discovery was announced on 16 December 2014, but the satellite was mistakenly designated before being immediately corrected to . orbits from Elektra with a period of 1.2 days—about two and a half times closer and four times quicker than the outer satellite Its roughly-circular orbit is inclined 156° with respect to the celestial equator. Preliminary simulations of the Elektra system show that 's semi-major axis oscillates less than over 20 years. Near-infrared observations from December 2014 show that along with display a similar spectrum to Elektra. S/2014 (130) 2 On 6 November 2021, astronomers A. Berdeu, M. Langlois, and F. Vachier reported the discovery of a third, closer-in satellite in archival VLT-SPHERE images taken between 9 and 31 December 2014, making Elektra the first quadruple system discovered and imaged in the main asteroid belt. This third satellite—which was provisionally designated —had eluded discovery when the images were taken, due to its faintness and close proximity to Elektra's bright glare. For these reasons, had to be measured through image subtraction of Elektra's
