  2. Earth's rotation - Wikipedia

    en.wikipedia.org/wiki/Earth's_rotation

    Earth's rotation imaged by Deep Space Climate Observatory, showing tilt. Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, Earth turns counterclockwise.

    The “Chandler Wobble” – a natural shifting of the Earth’s axis due to the planet not being perfectly spherical – could be linked to the spinning speeds, timeanddate.com reported.

  4. Foucault pendulum - Wikipedia

    en.wikipedia.org/wiki/Foucault_pendulum

    Foucault was inspired by observing a thin flexible rod on the axis of a lathe, which vibrated in the same plane despite the rotation of the supporting frame of the lathe. [ 2 ] The first public exhibition of a Foucault pendulum took place in February 1851 in the Meridian of the Paris Observatory .

  5. Rotation period (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Rotation_period_(astronomy)

    In astronomy, the rotation period or spin period [1] of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the sidereal rotation period (or sidereal day ), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars ( inertial space ).

    Earth has reportedly reached its quickest spin speeds in the past half-century.

  8. Axial precession - Wikipedia

    en.wikipedia.org/wiki/Axial_precession

    Earth rotates (white arrows) once a day around its rotational axis (red); this axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years [1] In astronomy , axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis .

    Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are causing feedback beneath the surface, impacting the planet's molten core.
