The Antarctic Circle is located at 66° 33′ 46″ south to the Equator line. The interesting fact about these Antarctic Circle trips is that, at least once a year, the sun stays above the horizon for 24 hours, which means there is no night for that day. On yet another day, the sun stays below the horizon, so there is no day for that night. What is the reason behind this unique event? The rotation axis of Earth has an inclination of 23° 26′ 14″ relative to the plane of Earth's orbit around the sun. Trips to the Antarctic Circle are generally offered by M/V Polar Pioneer, offering different travel options. M/V Ushuaia and M/V Plancius, among others, also reach the Antarctic Circle. These sailing trips take between 11 to 14 days depending on current weather conditions at the time of the trip.
