Chesterton Joins Named North Polar Craters
Yesterday, the MESSENGER team learned that the International Astronomical Union (IAU) had approved the name of another crater near Mercury's north pole. Chesterton, named for the English author Gilbert Keith Chesterton (1874-1936), joins nine other craters named in August 2012 in this region. Chesterton crater is identified with a green circle in the above image, and, like the other nine newly named polar craters, also hosts radar-bright deposits that may contain water ice.
