(Astronomy) astronomy Also called: obliquity of the … WebIn 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. fnf henry mod

Explanation: It is the angle between the plane of the Earth's equator and the plane of the Earth's orbit around the Sun. For the Earth, it is approximately 23∘27'. It varies slightly because of the force of gravity from the Moon and other planets in our solar system. WebBecause the Earth's equator is itself inclined at an angle of about 23.4° to the ecliptic (the obliquity of the ecliptic, ), these effects combine to vary the inclination of the Moon's orbit to the equator by between 18.4° and 28.6° over the 18.6 year period. green umbrella children\\u0027s foundation
