Earth obliquity
Did you know?
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… Web双语使用场景.

It is also called axial tilt or obliquity. Over 41000 years, the earth’s obliquity oscillates between 22.1 and 24.5 degrees. Currently, the earth’s obliquity is about 23.4%. thickers australiaWebAxial tilt (obliquity) The angle of the Earth's axial tilt (obliquity) varies with respect to the plane of the Earth's orbit. These slow 2.4° obliquity variations are roughly periodic, taking approximately 41,000 years to shift between a tilt of 22.1° and 24.5° and back again.
