Borealis quadrangle
The Borealis quadrangle is a quadrangle on Mercury surrounding the north pole down to 65° latitude (see also: geography of Mars).
It contains the Goethe Basin, whose diameter of at least makes it the sixth-largest impact basin observed on Mariner 10 images(Murray and others, 1974; Boyce and Grolier, 1977; Strom, 1977) and the seventh-largest known with the discovery of Skinakas Basin. The west half of the mapped area (between long 100° and 190° W.) is
Lyot (Martian crater)
Lyot is a large crater in the Vastitas Borealis region of Mars, located at 50.8° north latitude and 330.7° west longitude within the Ismenius Lacus quadrangle. It is 236 km in diameter. Its name refers to Bernard Lyot, a French astronomer (1897–1952).
Lyot crater, featuring a central peak in the middle, stands out on the flat plains of Vastitas Borealis, which is generally flat and smooth with few large craters. Lyot is the deepest point in the northern hemisphere
