  2. Earth's rotation - Wikipedia

    en.wikipedia.org/wiki/Earth's_rotation

    Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the gravity of the Sun, Moon and other bodies.

  3. Foucault pendulum - Wikipedia

    en.wikipedia.org/wiki/Foucault_pendulum

    The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault followed up in 1852 with a gyroscope experiment to further demonstrate the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities. [1]

  4. Earth - Wikipedia

    en.wikipedia.org/wiki/Earth

    Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth rotates around its own axis in slightly less than a day (in about 23 hours and 56 minutes). Earth's axis of rotation is tilted with respect to the perpendicular to its orbital plane around the Sun, producing ...

    We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion.

  6. Chandler wobble - Wikipedia

    en.wikipedia.org/wiki/Chandler_wobble

    The Chandler wobble or Chandler variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, [1] which was discovered by and named after American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth's surface and has ...

    Somewhat similarly, the friction of ocean tides from the moon’s gravitational pull slows the Earth’s rotation. Historically, that has had the largest influence on the planet’s rate of spin ...

  8. Earth’s core might be reversing its spin. It ‘won’t affect ...

    The discovery indicates that the Earth’s center regularly pauses and reverses its rotation, researchers in China wrote in a study published Jan. 23 in the journal Nature Geoscience.

  9. Diurnal motion - Wikipedia

    en.wikipedia.org/wiki/Diurnal_motion

    It is caused by Earth's rotation around its axis, so almost every star appears to follow a circular arc path, called the diurnal circle, [1] often depicted in star trail photography. The time for one complete rotation is 23 hours, 56 minutes, and 4.09 seconds – one sidereal day.
