The year that our nation declared its independence, in 1776, was the last time a total solar eclipse occurred only over the United States and in no other country,
This eclipse is particularly rare for its accessibility. The path of most total eclipses falls over water or unpopulated regions of the planet. The August event will go down as the first total solar eclipse whose path of totality stays completely in the United States since 1776, experts say, according the Space.com Total Solar Eclipse 2017 guide.
Total solar eclipses don’t often appear in the United States, which makes the coming event on August 21 all the rarer. This eclipse will travel in a thin 70-mile wide path across the entire nation, from Oregon to South Carolina.
The last time any part of the country experienced a total solar eclipse was nearly 40 years ago, on February 26, 1979. The path of the eclipse started in the Northwest, beginning in Washington and traveling east to North Dakota before moving into Canada.
