The 64th parallel south is a circle of latitude that is 64 degrees south of the Earth's equatorial plane. It crosses the Southern Ocean and the Antarctic mainland, the latter as the most northern latitude.
At this latitude the sun is visible for 21 hours, 1 minute during the December solstice and 4 hours, 12 minutes during the June solstice. [1]
Starting at the Prime Meridian and heading eastwards, the parallel 64° south passes through:

The 45th parallel south is a circle of latitude that is 45° south of the Earth's equator.
The 30th parallel north is a circle of latitude that is 30 degrees north of the Earth's equatorial plane. It stands one-third of the way between the equator and the North Pole and crosses Africa, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. The parallel is used in some contexts to delineate Europe or what is associated with the continent of Europe as a southernmost limit, e.g. to qualify for membership of the European Broadcasting Union.
The 55th parallel north is a circle of latitude that is 55 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
The 10th parallel north is a circle of latitude that is 10 degrees north of the Earth's equatorial plane. It crosses Africa, the Indian Ocean, the Indian Subcontinent, Southeast Asia, the Pacific Ocean, Central America, South America, and the Atlantic Ocean.
The 20th parallel north is a circle of latitude that is 20 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, North America, the Caribbean, and the Atlantic Ocean.
The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
The 30th parallel south is a circle of latitude that is 30 degrees south of the Earth's equator. It stands one-third of the way between the equator and the South Pole and crosses Africa, the Indian Ocean, Australia, the Pacific Ocean, South America and the Atlantic Ocean.
The 50th parallel south is a circle of latitude that is 50 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
The 60th parallel south is a circle of latitude that is 60 degrees south of Earth's equatorial plane. No land lies on the parallel—it crosses nothing but ocean. The closest land is a group of rocks north of Coronation Island of the South Orkney Islands, which are about 54 km south of the parallel, and Thule Island and Cook Island of the South Sandwich Islands, which both are about 57 km north of the parallel.

The 64th parallel north is a circle of latitude that is 64 degrees north of the Earth's equatorial plane. It crosses the Atlantic Ocean, Europe, Asia and North America.
The 66th parallel north is a circle of latitude that is 66 degrees north of the Earth's equatorial plane, about 61 km south of the Arctic Circle. It crosses the Atlantic Ocean, Europe, Asia and North America.
The 80th parallel north is a circle of latitude that is 80 degrees north of the Earth's equatorial plane, and 10 degrees south of the North Pole, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean, and North America.
