Every year, the moon, Earth's reliable celestial companion for 4.5 billion years, is getting 1.5 inches away. The distance to ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Just as passengers don’t feel the plane’s speed while smoothly cruising, we don’t feel Earth’s movement because we’re ...

Earth and the Moon are forever locked in a gravitational embrace that has played a critical role in determining the fate of both worlds. Although they have grown more distant since their formative ...

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 ...

The Earth isn't perfectly round IT'S FLAT. Ok not really, but it isn't as perfectly round as you'd expect from lessons in primary school or glancing briefly at a globe, either. First of all, why are ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

The European Space Agency (ESA)’s Juice mission is heading to Jupiter, but it isn’t traveling all that way in a straight line. Instead, like most solar system missions, the spacecraft makes use of the ...

For more than sixty years, a tiny asteroid has been moving in step with Earth, hidden from view until recently. Astronomers ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...
