NASA's Jet Propulsion Laboratory published an interesting note about the current state of Earth's axis tilt. The planet tilts on its axis, relative to the plane of the ecliptic (plane between the central mass of the Sun and the central mass of the planet), such that the plane does not intersect with the Equator except on Equinox dates. The spin axis has increased in length over the last century or so. Click this link to read more and to see a simulation of axial tilting.
