The Moon
The Moon is Earth’s only natural satellite—a rocky, cratered body about one‑quarter the diameter of Earth, orbiting at an average distance of approximately 384,400 km. It influences tides, stabilizes Earth’s axial tilt, and was formed about 4.5 billion years ago following a collision between Earth and a Mars-sized object.

APODs including "The Moon"
I Brought You the Moon
01/04/2018
I love you so much that I brought you the Moon. Please take it before this tree becomes more interested. Also, the Moon is heavier than I thought. And I foolishly picked it up by the hot side by mistake. But it is for you and, well, the others reading this APOD. Promise to keep this image -- our image -- in a safe place, and know that it was taken in a single, well-planned exposure in Valladolid, Spain. Please take it and keep it always as a token of our love and, well, April Fool's Day. Retrospective: April Fool's Day APODs
