The Moon, our constant celestial companion, is drifting away from Earth at a slow but measurable rate. According to a ...

In simple terms, ascending and descending orbits describe two modes of satellite flight relative to the Earth's rotation ...

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 ...

Due to the influence the Earth plays on the moon’s momentum, the Earth’s rotation slows down in response, as explained by DiKerby. However, given that this is such a minor change in distance annually, ...

Earth will complete its daily rotation between 1.25 and 1.51 milliseconds faster than usual, and scientists aren't quite sure why.

If you’re the kind of person who gets a lot done, you’re grateful for every one of the 86,400 seconds that make up a day. On July 9, however, as well as on July 22, and August 5, you won’t get your ...

Learn more about tides and tidal bulge, and how they’re contributing to the moon drifting away.

The Moon is slowly receding from Earth at 1.5 inches per year due to tidal forces. This celestial dance also causes Earth's ...

Precise orbit determination (POD) is vital for satellite navigation, positioning, and timing services, especially as large Low Earth Orbit (LEO) constellations grow in scale. A new method integrates ...

It wouldn’t be summer without the stretched out days. The dawns break early and the dusks come late, affording more time for lazy beach trips and long barbecues under the slow curve of the sun. But ...
