EARTH, MOON |
Soil is lower-case “earth.” And in most uses even the planet itself remains humbly in lower-case letters: “peace on earth.” But in astronomical contexts, the Earth comes into its own with a proud initial capital, and in science fiction it drops the introductory article and becomes “Earth,” just like Mars and Venus. A similar pattern applies to Earth’s satellite: “shine on, harvest moon,” but “from the Earth to the Moon.” Because other planets also have moons, it never loses its article.
