Where is Antarctic Circle? 10+ things to know about Antarctic Circle

Where is Antarctic Circle?

The Antarctic Circle is an imaginary line that marks the southernmost point on Earth where the sun is visible at least once a year on the winter solstice. It is located at a latitude of 66.33 degrees south of the Equator and encircles the Antarctic continent. This line marks the boundary of the region known as Antarctica, which is a landmass covered in ice and snow and is considered one of the coldest and most remote places on the planet. The Antarctic Circle experiences extreme cold temperatures, long periods of darkness during the winter, and 24-hour daylight during the summer. It is a critical line of latitude for scientists studying climate change, as the region plays a significant role in regulating global temperatures and sea levels.
