How the Earth Moves
Our spaceship Earth is in constant motion - rotating and revolving as it traverses through space. This is a story of our evolving understanding of the geography of Earth's position in space - a story of parallax, aberration and astrometry that stretches from the ancient Greeks to the most modern satellite, Gaia.
