    en.wikipedia.org/wiki/Seasons_on_planets

    Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.

  4. Year - Wikipedia

    en.wikipedia.org/wiki/Year

    Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn, and winter.

    en.wikipedia.org/wiki/Milankovitch_cycles

    The seasons are quadrants of the Earth's orbit, marked by the two solstices and the two equinoxes. Kepler's second law states that a body in orbit traces equal areas over equal times; its orbital velocity is highest around perihelion and lowest around aphelion. [13] The Earth spends less time near perihelion and more time near aphelion.

    en.wikipedia.org/wiki/Temperate_climate

    There is an equal climatic influence from both the polar and tropical zones in this climate region. Two types of climates are in this zone, a milder oceanic one and more severe seasonal continental one. Most prototypical temperate climates have a distinct four-season pattern, especially in the continental climate sector.

  8. Axial tilt - Wikipedia

    en.wikipedia.org/wiki/Axial_tilt

    This is the cause of Earth's seasons. Summer occurs in the Northern hemisphere when the north pole is directed toward the Sun. Variations in Earth's axial tilt can influence the seasons and is likely a factor in long-term climatic change (also see Milankovitch cycles). Relationship between Earth's axial tilt (ε) to the tropical and polar circles
