WebRadar and laser measures of the distance from Earth to the Moon have provided a recent value of the lunar parallax. Radar and laser ranges have the advantage of being a direct distance measure, although the ranges are affected by variations in the surface topography of the Moon and require assumptions about the lunar radius and the centre of mass.
