Web"Obliquity and Precession for the Last 5000000 Years": For the past 5 million years, Earth's obliquity has only varied between 22° 02' 33" and 24° 30' 16". So whatever the cause it seems the Earth's angle is quite stable. Without our 23° we wouldn't have seasons or longer nights and shorter days throughout the years. WebMilutin Milankovitch.

As the orbit gets more eccentric (oval) the …
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane and orbital plane. It differs from orbital inclination. At an obliquity of 0 degrees, the two axes point in the same direction; that is, the rotational axis is perpendicular to the orbital pla… WebFeb 27, 2024 · Milankovitch cycles include the shape of Earth’s orbit (its eccentricity), the angle that Earth’s axis is tilted with respect to Earth’s orbital plane (its obliquity), and …
