    S/2003 J 24 (temporarily designated EJc0061) is a moon of Jupiter, discovered by Scott S. Sheppard et al. in 2003. It was independently found by amateur astronomer Kai Ly, who reported it on June 30, 2021. [1] [2] It was formally announced on 15 November 2021 in the MPEC. [3]

    Ly had previously recovered four "lost" moons of Jupiter in 2020: S/2003 J 23, S/2003 J 12, S/2003 J 4, and S/2003 J 2. [4]

    S/2003 J 24 orbits Jupiter at an average distance of 23,088,000 km (0.15433 AU) in 715.4 days, at an inclination of 162° to the ecliptic, in a retrograde direction and with an eccentricity of 0.25.

    It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.

    Valetudo, also known as Jupiter LXII and originally known as S/2016 J 2, is a moon of Jupiter. It was discovered by Scott S. Sheppard and his team in data acquired by the 6.5-m Magellan-Baade telescope of the Las Campanas Observatory in 2016, but was not announced until 17 July 2018, via a Minor Planet Electronic Circular from the Minor Planet Center, which also reported the discovery of nine other Jupiter moons. Besides data from Las Campanas, the original announcement also referred to data acquired through the 8.1-m Gemini North telescope — of the Mauna Kea Observatories — as well as the 4.0-m reflector of the Cerro Tololo Inter-American Observatory.
