  2. Celestial mechanics - Wikipedia

    en.wikipedia.org/wiki/Celestial_mechanics

    The common noun ‘moon’ (not capitalized) is used to mean any natural satellite of the other planets. Tidal force is the combination of out-of-balance forces and accelerations of (mostly) solid bodies that raises tides in bodies of liquid (oceans), atmospheres, and strains planets' and satellites' crusts.

  3. Astronomical nutation - Wikipedia

    en.wikipedia.org/wiki/Astronomical_nutation

    Basically, there are also torques from other planets that cause planetary precession which contributes to about 2% of the total precession. Because periodic variations in the torques from the sun and the moon, the wobbling (nutation) comes into place. You can think of precession as the average and nutation as the instantaneous.

  4. Nodal precession - Wikipedia

    en.wikipedia.org/wiki/Nodal_precession

    The rate of precession depends on the inclination of the orbital plane to the equatorial plane, as well as the orbital eccentricity.. For a satellite in a prograde orbit around Earth, the precession is westward (nodal regression), that is, the node and satellite move in opposite directions. [1]

  5. Retrograde and prograde motion - Wikipedia

    en.wikipedia.org/wiki/Retrograde_and_prograde_motion

    All eight planets in the Solar System orbit the Sun in the direction of the Sun's rotation, which is counterclockwise when viewed from above the Sun's north pole. Six of the planets also rotate about their axis in this same direction. The exceptions – the planets with retrograde rotation – are Venus and Uranus.

  6. 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.

    That has upset some current, part-time Air National Guard members involved in space missions because the proposed move would force them into the full-time, active-duty Space Force. Show comments ...

  9. Equatorial bulge - Wikipedia

    en.wikipedia.org/wiki/Equatorial_bulge

    The forces at play in the case of a planet with an equatorial bulge due to rotation. Red arrow: gravity Green arrow: the normal force Blue arrow: the resultant force The resultant force provides required centripetal force. Without this centripetal force frictionless objects would slide towards the equator.
