The moon was named in 2019 after Ersa, the Greek goddess of dew, daughter of Zeus and Selene: Jupiter L Herse is also named for this goddess. The name was suggested in a naming contest held by the Carnegie Institute on Twitter where more than twenty tweets suggested the name, including Aaron Quah (@8603103) who submitted the name first, StSauveur_MoonsProject (@StSauMoons) that are the 12th grade students of Saint Sauveur High School in Redon, France, the fifth grade at Hillside Traditional Academy in British Columbia, Canada (submitted on their behalf by @mrgrouchypants), and a 4-year-old child who sang a song about Ersa (submitted on his behalf by @Thoreson).
