This impact set the angular momentum for the Earth-moon system, and gave the early Earth a five-hour day. Over millennia, the moon has receded from the Earth and the rotation has slowed to our current ...

Here we refer to the giant-impact theory in which the Earth–Moon post-impact angular momentum (AM ... The AM of the system is set by the impact, and the Moon accretes from the disk, which ...

The Moon’s increasing distance has to do with a physics concept called angular momentum, which is a body’s resistance to a change in its rotation or orbit. If we look at the Earth-Moon system ...

making up the angular momentum of the Earth-moon system, said physicist Richard Olenick. Angular momentum remains constant for such fairly isolated systems as Earth and moon; therefore ...

It boils down to one of Newton’s laws: conservation of angular momentum ... which must expand to conserve the total momentum of the Earth-Moon system. The Moon is moving away from Earth at ...

Since the mystery push was pointed through the center of mass of the Earth-moon system, it didn’t change the angular momentum of the system. Angular momentum is a measure of rotational motion ...

"Since the Earth and the moon are part of the same gravitationally interacting system, total angular momentum must be conserved — stay the same — between the two," Broome explained.

Later, Jack Wisdom of the Massachusetts Institute of Technology suggested several alternate scenarios for draining angular momentum away from the Earth-moon system. But none of the explanations ...

Based on our current best understanding, the solar system formed from a primordial ... to account for five things: the ...

but for the solar system, that's huge. No other moon is that large relative to its parent planet. The oddities don't stop there. The total angular momentum of Earth's spin, the moon's spin and the ...
