Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2009
NAVAL OBSERVATORY WASHINGTON DC
Pagination or Media Count:
Every three years the IAU Working Group on Cartographic Coordinates and Rotational Elements revises tables giving the directions of the poles of rotation and the prime meridians of the planets, satellites, minor planets, and comets. This report takes into account the IAU Working Group for Planetary System Nomenclature WGPSN and the IAU Committee on Small Body Nomenclature CSBN definition of dwarf planets, introduces improved values for the pole and rotation rate of Mercury, returns the rotation rate of Jupiter to a previous value, introduces improved values for the rotation of five satellites of Saturn, and adds the equatorial radius of the Sun for comparison.
