About 115 miles wide as it races across Earth’s surface, the path of totality will cross parts of four states in Mexico (Sinaloa, Nayarit, Durango and Coahuila), 15 U.S. states (Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Tennessee, Michigan, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine) and seven Canadian Provinces (Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia and Newfoundland). In the U.S., totality will begin in Texas at 1:27 pm CDT and end in Maine at 3:35 pm EDT.Â

4. Tennessee and Michigan get only a technical totality
The path of totality touches a small corner of Tennessee and Michigan. In Tennessee, only the northwest corner is in the path, with a maximum of 2 minutes and 7 seconds at Kentucky Bend/New Madrid Bend. In Michigan, only the southeast corner is in the path, with 1 minute 20 seconds at the exclave of Lost Peninsula Marina. Â
5. A tiny village in Mexico will get the best view
Within any path of totality is a center point, a point of maximum eclipse, where a total solar eclipse will be experienced around midday with the sun and moon at their highest in the sky. It’s here where the geometry of the sun, moon, and Earth line up precisely, meaning the slowest-moving shadow — and so the longest totality.Â
On April 8, that point is just 4 miles (6 kilometers) to the north of Nazas, population 3,600, in the Mexican state of Durango. From here, totality will last 4 minutes and 28 seconds.Â
6. It’s part of a repeating event in North America
Solar eclipses come in families called Saros (Greek for repetition). Every 6,585.3 days, a shadow of the moon hits Earth of roughly the same proportions as the previous one. The only reason it doesn’t occur in the same place is that .3 of a day (around 8 hours), which means Earth has rotated slightly.Â
The total solar eclipse on April 8 is part of Saros 139, which 6,585.3 days previously, on March 29, 2006, produced an almost identical totality for Africa and Asia. The next eclipse in Saros 139 after 2024 will occur on April 20, 2042, when totality is visible from Indonesia, Eastern Malaysia, Brunei and the Philippines.Â
However, every fourth repetition (54 years), a total solar eclipse occurs in roughly the same place, something called an exeligmos:Â
March 7, 1970: Mexico, the U.S. (Florida, Georgia, South Carolina, North Carolina, Massachusetts) and Canada (Nova Scotia and Newfoundland)Â May 11, 2078: Mexico, the U.S. (Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina and Virginia)Â 7. Seasons determine the path of totality

Look at the central paths of the two solar eclipses that will strike North America within six months — the annular solar eclipse on October 14, 2023, and the total solar eclipse on April 8, 2024.Â
One shadow moves northwest-southeast, and the other moves southwest-northeast, but why? Though the position and distance of the moon have a huge effect on the eclipse, the differing orientation of the paths is down to Earth’s titled axis, which is leaning different ways during both eclipses. In October (fall), the Earth moves downwards as it rotates, while in April (spring), it moves upwards.Â
8. It’s a ‘city eclipse’
About 40 million people live within the path of totality on April 8, around three-quarters of them in the U.S. Major cities inside the path include Mazatlan and Torreon in Mexico, San Antonio, Austin, Dallas-Fort Worth, Indianapolis, Little Rock, Cleveland, Buffalo and Rochester in the U.S. and Hamilton and Montreal in Canada. That accounts for about 10 million people. However, there are also many huge cities close to the path of totality, whose residents only have to drive very short distances to experience totality — something eclipse-chasers travel worldwide to experience. St Louis, Cincinnati, Toronto and Quebec are very close to the path, while the inhabitants of Houston, Chicago, Detroit, Boston, New York, Philadelphia, Baltimore, and Washington, D.C., are all within 200 miles of the path of totality.Â
9. Alaska misses out on totality — but not for long
Neither of the two non-contiguous U.S. states will see a total solar eclipse on April 8. Hawaii will see a 20% partial solar eclipse at sunrise. In comparison, only southeast Alaska west of Juneau — including Glacier Bay National Park and Preserve — will see up to a 5% partial solar eclipse mid-morning. However, Alaska will only have to wait until just after sunrise on March 30, 2033 — almost exactly 9 years later — before it sees a total solar eclipse. A maximum of 2 minutes and 37 seconds of totality will be experienced, with key observing locations within a 500-mile wide path of totality, including UtqiaÄ¡vik, Kotzebue, Nome and St Lawrence Island.Â
10. The U.K. will have the last view of the eclipse
Few will notice it, but this total solar eclipse for North America ceases to exist on the west coast of the U.K. A sunset commences on April 8, from the west coast of Wales, England, and Scotland, where it will be possible to see a tiny bite taken from the sun in the slightest of partial solar eclipses. A very low view of the horizon will be required — in practice, an ocean horizon — as well as clear skies.Â
