Artemis is the Greek goddess of the hunt, wild animals and the moon, twin sister of Apollo; the name is of uncertain origin, and ancient writers linked it to artemes, "safe" or "unharmed". NASA's Artemis program, which aims to return astronauts to the moon, has brought the name back into the news. In the United States Artemis rose from number 1921 in 2015 into the top 1000 in 2020, peaked at number 854 in 2023 and ranks number 1017 in 2025.
