Who named our planets?
Except for the name Earth, our planets' names come from Roman and Greek mythology. The five planets easily visible to the naked eyeMercury, Venus, Mars, Jupiter, and Saturnwere called different things by different cultures. The Romans named these planets, meaning “wanderers,” according to their movements and appearance. For example, they named Jupiter after the king of the gods; they named Venus, the planet that appears the brightest, after the Roman goddess of beauty; they named the reddish Mars after the god of war. Saturn is named after the god of agriculture. These Roman names were adopted by European languages and culture and became standard in science.
