Due to the Earth’s tilt relative to the Sun, the solar declination line oscillates between the Tropic of Cancer (located at latitude 23.4° North) and the Tropic of Capricorn (located at latitude 23.4° South). This diagram shows how the tilt of Earth's axis aligns with incoming sunlight around the winter solstice of the Northern Hemisphere.
Diagram of the Earth's seasons as seen from the south. Far left: June solstice. The equinoxes are the only times when the solar terminator (the "edge" between night and day) is perpendicular to the equator.
This is a diagram of the seasons. Regardless of the time of day (i.e. Earth 's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter . Figure 3 shows the angle of sunlight striking Earth in the Northern and Southern Hemispheres when Earth's northern axis is tilted away from the Sun ...
By astronomical convention, the four seasons are determined by the solstices (the two points in the Earth's orbit of the maximum tilt of the Earth's axis, toward the Sun or away from the Sun) and the equinoxes (the two points in the Earth's orbit where the Earth's tilted axis and an imaginary line drawn from the Earth to the Sun are exactly ...
Jun. 26—This week marks the end of June and we are heading rapidly around the sun. Because our planet has that interesting tilt to it, the northern hemisphere is collecting many hours of ...

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. [14] The Earth spends less time near perihelion and more time near aphelion.
