The dusk subcategory
The sunset time is defined in astronomy as the time when the trailing edge of the Sun disk disappears below the horizon. Close to the horizon, atmospheric refraction causes the path of rays of light from the Sun to be distorted in such a way that geometrically the Sun disk is already about one diameter below the horizon at sunset is observed.
The sun sets differ from the twilight, which has three phases, the first being the civilian twilight, which begins as soon as the Sun has disappeared under the horizon, and continues down to 6 degrees below the horizon; The second stage is the nautical twilight, between 6 and 12 degrees below the horizon; and the third is the twilight of astronomy, the period in which the Sun lies between 12 and 18 degrees below the horizon. [1] Dusk is at the edge of the twilight of astronomy, and is the darkest nightfall before night. [2] Night occurs as the sun reaches 18 degrees below the horizon and no longer illuminates the sky.
Locations north of the Arctic Circle and south of the Antarctic Circle do not experience sunset or sunrise at least one day in a year, when polar or polar nights continue for 24 hours.
The sun sets create unique atmospheric conditions such as the often intense orange and red colors of the Sun and the surrounding sky.
