text: 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.
text: Earth's axial tilt (obliquity) is currently about 23.4°.
text: 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.
text: In addition to causing seasons, this axial tilt (known as obliquity) allows sunlight to fully illuminate the poles--periodically even at midnight--so that over a year, remote-sensing satellites can image the entire surface of our planet.
text: Because of Earth's axial tilt (obliquity), our planet orbits the Sun on a slant which means different areas of Earth point toward or away from the Sun at different times of the year.
