Valetudo (moon)

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 of Jupiter's moons.

[1] 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.

Sheppard proposed the name Valetudo, after the Roman goddess of health and hygiene (a Latin translation of Greek Hygieia 'Health') and a great-granddaughter of the god Jupiter.

The name also alluded to Sheppard's girlfriend, whom he joked about being cleanly.

[8] The name was approved by the IAU Working Group for Planetary System Nomenclature on 3 October 2018.

Jupiter moons are indicated in red and can be clustered into five groups plus the solitary moons Valetudo and Themisto , which suggests that the current Jupiter moons originate from at least seven different outer moons.
