Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...
So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

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 ...
Earth has a new friend — and it's been waiting for us to notice it for decades. In a new study published in the journal ...
Skygazers, get ready to head outside and spot the supermoon, coming in October.
Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.
Every year, the moon, Earth's reliable celestial companion for 4.5 billion years, is getting 1.5 inches away. The distance to ...
The Soviet Union’s successful Zond-5 space mission in 1968 prompted NASA to speed up the Apollo program—ultimately driving it ...
The Moon, our constant celestial companion, is drifting away from Earth at a slow but measurable rate. According to a ...
