The
Astronomia nova (full title in original
Latin:
Astronomia Nova ΑΙΤΙΟΛΟΓΗΤΟΣ seu physica coelestis, tradita commentariis de motibus stellae Martis ex observationibus G.V. Tychonis Brahe) is a book, published in 1609, that contains the results of the astronomer
Johannes Kepler's ten-year-long investigation of the motion of
Mars. One of the greatest books on
astronomy, the
Astronomia nova provided strong arguments for
heliocentrism and contributed valuable insight into the movement of the planets, including the first mention of their elliptical path and the change of their movement to the movement of free floating bodies as opposed to objects on rotating spheres. It is recognized as one of the most important works of the
Scientific Revolution.
