The path of totality is the track of the Moons shadow across Earths surface during a total solar eclipse. It is the area where the total solar eclipse can be seen, and it is typically about 16,000 kilometers (about 10,000 miles) long. During a total solar eclipse, the sun is entirely and perfectly blocked by the moon, which in turn casts a shadow on Earth. The path of totality is a narrow band that stretches across the Earths surface, and it is the only place where the total solar eclipse can be seen in its entirety. The path of totality for the next total solar eclipse, which will occur on April 8, 2024, will cross from Mexico, through the United States from Texas to Maine, and up through Canada. The duration of totality will last approximately two minutes, depending on where you are viewing the eclipse. To determine the precise start time, end time, and duration of totality for your exact location on eclipse day, you can use interactive Google eclipse maps developed by Xavier Jubier.
