The northernmost land on earth, whether the permanent Kaffeklubben Island, or the shifting/resubmerging gravel banks of Oodaaq, ATOW1996, or 83-42, all of which are part of Greenland, are roughly 40 minutes of arc (75 to 79 kilometres) north of this parallel.
At this latitude the sun is visible Midnight sun during the summer solstice and Polar night during the winter solstice.

The northernmost land on earth, Kaffeklubben Island, Greenland, is roughly 40 kilometres south of the 84th parallel.
At the 84th and 85th parallels, the sun is visible for 24 hours, 0 minutes during the summer solstice. During the winter solstice, the 84th parallel is under astronomical twilight, and the 85th parallel is under total nighttime during the entire day. The 85th parallel is the first parallel by degree to do this. The Arctic Circle is the latitude where the center of the sun is visible at midnight during the summer solstice, as opposed to the entire disk.
