  2. Axial tilt - Wikipedia

    en.wikipedia.org/wiki/Axial_tilt

    Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. [6] It is denoted by the Greek letter Epsilon ε. Earth currently has an axial tilt of about 23.44°. [7]

  3. Axial precession - Wikipedia

    en.wikipedia.org/wiki/Axial_precession

    For example, suppose that the Earth's orbital position is marked at the summer solstice, when the Earth's axial tilt is pointing directly toward the Sun. One full orbit later, when the Sun has returned to the same apparent position relative to the background stars, the Earth's axial tilt is not now directly toward the Sun: because of the ...

    en.wikipedia.org/wiki/Milankovitch_cycles

    The angle of the Earth's axial tilt with respect to the orbital plane (the obliquity of the ecliptic) varies between 22.1° and 24.5°, over a cycle of about 41,000 years. The current tilt is 23.44°, roughly halfway between its extreme values.

    The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the Earth’s tilt of roughly 31.5 inches. The ...

  8. Earth - Wikipedia

    en.wikipedia.org/wiki/Earth

    Earth's axial tilt causing different angles of seasonal illumination at different orbital positions around the Sun. The axial tilt of Earth is approximately 23.439281° [2] with the axis of its orbit plane, always pointing towards the Celestial Poles. Due to Earth's axial tilt, the amount of sunlight reaching any given point on the surface ...

  9. Cataclysmic pole shift hypothesis - Wikipedia

    en.wikipedia.org/wiki/Cataclysmic_pole_shift...

    The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
