I found a whole lot of lovely websites devoted to English errors today. My favourites:
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.

It baffles me to this day. Is it an obscure form of second person, like the vosotros tense? A pun on “urine” perhaps?
