A total solar eclipse will occur on December 4, 2021. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. This eclipse will be unusual as the path of the total eclipse will move from east to west across Antarctica, while most eclipse paths move from west to east. This reversal is only possible in polar regions.
