A total solar eclipse will occur at the Moon's descending node of orbit on Friday, January 5, 2057,[1] with a magnitude of 1.0287. 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. Occurring about 1.6 days after perigee (on January 3, 2057, at 20:00 UTC), the Moon's apparent diameter will be larger.[2]
This eclipse and May 20, 2050 are the next two total solar eclipses in which the Moon's shadow will trace a path that fails to hit land anywhere on Earth. Totality will begin 125 miles east of Belmonte in Brazil, then traverse southeast through the Atlantic Ocean where it will miss the Cape of Good Hope in South Africa by 250 miles, before winding northeast and concluding in the Indian Ocean 500 miles south of Java island. However, a partial solar eclipse will be visible for parts of eastern South America, Southern Africa, Antarctica, Southeast Asia, and western Australia.
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the Moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[3]

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
