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°.
But Earth's axis tilt doesn't change either. What does change is Earth's orientation relative to the Sun. While Earth spins on its axis, it is also traveling around the Sun in orbital revolution. One full orbit around the sun is about 365 Earth days, or one year.ecause of Earth's spherical shape and axis tilt, incoming radiation is not absorbed evenly across the planet, and this distribution changes with the seasons. Earth's rotation is the cause for the differences in daytime and nighttime as it spins on its axis.
