Doing the Wobble Earth's spin has a bit of a wobble to it, as the axis drifts at the poles. The spin has been drifting faster than normal since 2000, NASA has measured, moving 7 inches (17 cm) per year to the east. Scientists determined that it continued east instead of going back...

But they could also help explain why Earth is rotating faster and faster over time. Discovered in the 1800s, the Chandler Wobble points to a natural jiggle in Earth’s movement. Researchers haven’t been able to point to a singular cause, but it could be due to the fact that Earth isn...
Modeling of nutation and precession: New nutation series for nonrigid Earth and insights into the Earth's interior [1] The analytical formulation of the theories of nutation and wobble reveals the combinations of basic Earth parameters that govern the nutation-wobble re... PM Mathews,TA Herring,...
We have also looked for evidence of spacecraft ''wobble'' which demonstrates that the source of a bright or dark feature in the images is external to the camera, but found none for dark pixels. Finally, we studied the bright streaks that frequently appear in UVI images, sometimes comet-...
What are the three processes that make up Milankovitch cycles and approximately how long is each of these cycles? a. Wobble in the Earth's axis (26,000 years) b. Changes in the Earth's tilt (200 years) c. Changes in the Earth's tilt (41,000 years) d. Wobb ...
Why does the solstice date change? The exact orbital and daily rotational motion of the Earth, such as the 'wobble' in the Earth's axis (precession), also contributes to the changing solstice dates. The solstices occurbecause the rotation axis of the Earth is tilted by an angle of 23.5 ...
La Laguna (ULL), and Martín López Corredoira, questions one of the most interesting findings about the dynamics of theMilky Wayin recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect. The results have just been published inTheAstrophysical ...
By the year 6430, perihelion will fall on the March equinox (March 20), according to Time and Date. Orbital precession is essentially a gradual shift of the perihelion point around the sun. Like a wobble of a spinning top, the perihelion point slides around the barycenter with every ...
global news wasn’t her achievement — a 12-day stint in space — but rather two embarrassing moments spurred by disorientation and syncope. The fifth of six speakers, she wobbled twice and almost tumbled to the ground while talking. Heidemarie had yet to completely readjust to Earth’s ...
