Earth's obliquity today
Did you know?
WebEccentricity is a characteristic of Earth’s orbit around the Sun. Obliquity is angle between Earth’s spin axis and the normal to ecliptic. What is obliquity in science? Obliquity relates to a planet’s plane of orbit. As an orbiting planet spins on its axis, obliquity is the angle between a perpendicular to its orbital plane and its spin ... WebThree key results emerge at high obliquity: (1) despite reversed temperature gradients, mid-latitudes surface winds are westerly and trade winds exist at the equator (as for phi = 23.5) although the westerlies are confined to the summer hemisphere, (2) a habitable planet is possible with mid-latitude temperatures in the range 300-280 K and (3) a …

Obliquity is why Earth has seasons. Over the last million years, it has varied between 22.1 and 24.5 degrees perpendicular to Earth’s orbital plane. The greater Earth’s axial tilt angle, the more extreme our seasons are, as each hemisphere ...

(higher latitude means both poles, just for clarity, high latitude = far from equator) High obliquity means more extreme seasonality (hotter summers and colder winters in both hemispheres).
