The question of our unusual ... Earth's gravity. Astronomers Darren Williams and Michael Zugger of Pennsylvania State University have crunched some numbers and found that the gravitational capture ...

"The moon is more in line with the sun than it is with the Earth's equator," Williams said. Providing their binary-exchange capture theory, the two of them believe Earth's gravity separated the ...

When teachers explain ocean tides, they frequently describe how the moon's gravity pulls on Earth and all of its water. This, they often say, leads to a gravitational imbalance, which stretches ...

Capture theory suggests that the Moon was a wandering body (like an asteroid) that formed elsewhere in the solar system and was captured by Earth's gravity as it passed nearby. The accretion ...
