how much distance from the earth to the moon and where is moon?
Earth’s Moon Earth’s partner in its yearly trek around the Sun, the Moon, is geologically dead. Dried lava fields called “maria” — Latin for seas — cover its surface, along with impact craters. The maria formed about four billion years ago, when giant asteroids punched holes in the Moon’s crust, allowing molten rock to bubble to the surface, where it cooled and hardened. The mountains of Taurus-Littrow dwarf the Apollo 17 Moon lander, Challenger (at center). Earth and the Moon are more like a double planet than a planet and a moon. The Moon is quite large in comparison to Earth — about one-quarter of Earth’s diameter. The two gravitationally interact with each other, most famously causing Earth’s ocean tides. The interaction has other important consequences. Over time, the Moon’s rotation has become tidally locked, so that the same side of the Moon always faces Earth. And the Moon acts to stabilize a “wobble” in Earth’s axis. Over billions of years, this has led to a much more stabl
