Circles of latitude between the 50th parallel south and the 55th parallel south
Following are Circles of latitude between the 50th parallel south and the 55th parallel south. These circles of latitude generally pass through Chile and Argentina, and through minor outlying islands in Oceania.

The 51st parallel south is a circle of latitude that is 51 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
At this latitude the sun is visible for 16 hours, 33 minutes during the December solstice and 7 hours, 55 minutes during the June solstice.[1]

53rd parallel south
[edit]The 53rd parallel south is a circle of latitude that is 53 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
At this latitude the sun is visible for 16 hours, 56 minutes during the December solstice and 7 hours, 34 minutes during the June solstice. Approximately 53º18' South, 33 km (21 mi) south of this parallel, during the December summer solstice, the sun is visible for 17 hours exactly. If the latitude in the southern hemisphere is 53º47' or smaller, it is possible to view both astronomical dawn and dusk every day of the month of February.[3]

[edit]Starting at the Prime Meridian and heading eastwards, the parallel 53° south passes through:
54th parallel south
[edit]The 54th parallel south is a circle of latitude that is 54 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
At this latitude the sun is visible for 17 hours, 9 minutes during the December solstice and 7 hours, 22 minutes during the June solstice.[4]

[edit]Starting at the Prime Meridian and heading eastwards, the parallel 54° south passes through:
55th parallel south
[edit]The 55th parallel south is a circle of latitude that is 55 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, the Indian Ocean, the Pacific Ocean and South America.
At this latitude the sun is visible for 17 hours, 22 minutes during the December solstice and 7 hours, 10 minutes during the June solstice.[5]
The longest continuous east–west distance at sea is along this latitude, at 55°59'S. (see Extremes on Earth § Along constant latitude)
