In astronomy, axial tilt, known to astronomers as obliquity, is the angle between an object's rotational axisand its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs fromorbital inclination. In the Earth, the axis causes in summer 24- hour days and in winter 24-hour nights. Example countries: Sweden, Norway and Finland.
