Solar eclipse of July 1, 2057
An annular solar eclipse will occur at the Moon's ascending node of orbit between Sunday, July 1 and Monday, July 2, 2057, with a magnitude of 0.9464. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus. An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 1.7 days after apogee, the Moon's apparent diameter will be smaller.
The path of annularity will be visible from parts of northwest China, Mongolia, eastern Russia, northern Alaska, western and central Canada, and far northeast Minnesota, northern Michigan, and far western New York in the United States. A partial solar eclipse will also be visible for parts of East Asia, Northeast Asia, Northern Europe, and North America.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| June 17 Descending node | July 1 Ascending node |
| Partial lunar eclipse Lunar Saros 121 | Annular solar eclipse Solar Saros 147 |
