# Solar eclipse of January 5, 2057

A total solar eclipse will occur at the Moon's descending node of orbit on Friday, January 5, 2057, 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.
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.

## 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.
Eclipse season of December 2056–January 2057 :
| December 22 Ascending node (full moon) | January 5 Descending node (new moon) |
| Penumbral lunar eclipse Lunar Saros 116 | Total solar eclipse Solar Saros 142 |

### Solar eclipses of 2054–2058

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.
The partial solar eclipses on March 9, 2054 and September 2, 2054 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 22, 2058 and November 16, 2058 occur in the next lunar year eclipse set.
Solar eclipse series sets from 2054 to 2058 :

### Saros 142

This eclipse is a part of Saros series 142, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on April 17, 1624. It contains a hybrid eclipse on July 14, 1768, and total eclipses from July 25, 1786 through October 29, 2543. There are no annular eclipses in this set. The series ends at member 72 as a partial eclipse on June 5, 2904. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of totality will be produced by member 38 at 6 minutes, 34 seconds on May 28, 2291. All eclipses in this series occur at the Moon’s descending node of orbit.

### Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
Series members between 1801 and 2200 :
| December 21, 1805 (Saros 119) | November 19, 1816 (Saros 120) | October 20, 1827 (Saros 121) | September 18, 1838 (Saros 122) | August 18, 1849 (Saros 123) |

### Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
Series members between 1801 and 2200 :
