The Tropic of Cancer, also known as the Northern Tropic, is the Earth's northernmost circle of latitude where the Sun can be seen directly overhead. This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent. It also reaches 90 degrees below the horizon at solar midnight on the December Solstice. Using a continuously updated formula, the circle is currently 23°26′09.8″ (or 23.43606°) north of the 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 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 70th parallel north is a circle of latitude that is 70 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.
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 66th parallel north is a circle of latitude that is 66 degrees north of the Earth's equatorial plane, about 61 kilometres (38 mi) south of the Arctic Circle. It crosses the Atlantic Ocean, Europe, Asia and North America.
The 67th parallel north is a circle of latitude that is 67 degrees north of the Earth's equatorial plane, about 50 km north of the Arctic Circle. It crosses the Atlantic Ocean, Europe, Asia and North America.
The 69th parallel north is a circle of latitude that is 69 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia and North America, and passes through some of the southern seas of the Arctic Ocean.
The 72nd parallel north is a circle of latitude that is 72 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America.
The 73rd parallel north is a circle of latitude that is 73 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America.
The 74th parallel north is a circle of latitude that is 74 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean, and North America.
The 75th parallel north is a circle of latitude that is 75 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America.
The 76th parallel north is a circle of latitude that is 76 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America.
The 77th parallel north is a circle of latitude that is 77 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, Europe, Asia, the Arctic Ocean and North America. It is the northernmost integral parallel that passes through continental mainland.
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.
The 81st parallel north is a circle of latitude that is 81 degrees north of the Earth's equatorial plane, in the Arctic. It crosses the Atlantic Ocean, the Arctic Ocean, Europe, Asia and North America.
The 85th parallel north is a circle of latitude that is 85 degrees north of the Earth's equatorial plane, in the Arctic. This parallel lies entirely within the Arctic Ocean.
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth at about 66° 34' N. Its southern equivalent is the Antarctic Circle.
