The Earth stands alone in the solar system as a habitable world, as far as we know. But that doesn’t mean we don’t get visitors, most often in the form of (usually harmless) asteroids. Some even ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...
