Chesterton is a crater on Mercury, near the north pole. Its name was adopted by the International Astronomical Union in 2012, after the English author G. K. Chesterton.[1]
The floor of the crater is in permanent shadow. S band radar data from the Arecibo Observatory collected between 1999 and 2005 indicates a radar-bright area covering the entire floor of Chesterton, which is probably indicative of a water ice deposit.[2][3][4]
Chesterton is adjacent to Tryggvadóttir crater.
