How the Planets and Satellites Got Their Names
Named for the winged Roman god of travel because it appears to move so swiftly.
Roman name for the goddess of love. This planet was considered to be the brightest and most beautiful planet or star in the heavens.
The name Earth comes from the Indo-European base 'er,' which produced the Germanic noun 'ertho,' and ultimately German 'erde,' Dutch 'aarde,' Danish and Swedish 'jord,' and English 'earth.' Related forms include Greek 'eraze,' meaning 'on the ground,' and Welsh 'erw,' meaning 'field.'
THE MOON: Every civilization has had a name for the satellite of Earth that is known, in English, as the Moon. The name is of Anglo-Saxon derivation.
