In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane.It differs from orbital inclination.arth 's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. It is denoted by the Greek letter Îµ. Earth currently has an axial tilt of about 23.4Â°.
The Tilt of the Earth's Axis and its Elliptical Orbit We have all been taught that the seasons are caused by the 23.4Â° angular offset (obliquity) between the Earth's axis of rotation and a perpendicular to the Earth's orbital plane with the Sun (see obliquity below).
