Tryggvadóttir is a crater on Mercury. The north pole of Mercury is located next to its northern rim. It was named by the IAU in 2012 after the Icelandic artist Nína Tryggvadóttir.[1]
All but the rim 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 Tryggvadóttir, which is probably indicative of a water ice deposit.[2][3][4]
Tryggvadóttir is adjacent to the larger Tolkien crater and to Chesterton crater.
