Where will the total solar eclipse be visible ? The path of totality for the Aug. 21, 2017 , total solar eclipse is about 70 miles wide and stretches from Oregon to South Carolina. It passes through Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and South Carolina.

The path of this shadow, the path of totality , is where observers will see the Moon completely cover the Sun for about two and a half minutes. The animation provides an overhead view of the umbra and runs at a rate of 30× real time — every minute of the eclipse takes two seconds in the animation.
During the August 21, 2017 total solar eclipse, the Moon’s umbral shadow will fly across the United States, from Oregon to South Carolina, in a little over 90 minutes. 2017 Path of Totality .

In a solar eclipse , the Moon moves between the Earth and the Sun . When this happens, part of the Sun’s light is blocked. The sky slowly gets dark as the Moon moves in front of the Sun . When the Moon and Sun are in a perfect line, it is called a total eclipse .
But not everyone experiences every solar eclipse . Getting a chance to see a total solar eclipse is rare. The moon’s shadow on Earth isn’t very big, so only a small portion of places on Earth will see it. You have to be on the sunny side of the planet when it happens.
During the brief period of totality, when the sun is completely covered, the beautiful corona — the tenuous outer atmosphere of the sun — is revealed. Totality may last as long as 7 minutes 31 seconds , though most total eclipses are usually much shorter.
Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse . As a result, you are more likely to see a lunar eclipse than a solar eclipse .
An eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. There are two types of eclipses on Earth: an eclipse of the moon and an eclipse of the sun. What Is a Lunar Eclipse ? The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun.
During the eclipse , food, water should not be taken. Do not bathe during the eclipse . Take a bath after the eclipse ends. Do not look at the eclipse with open eyes.
Exposing your eyes to the sun without proper eye protection during a solar eclipse can cause “ eclipse blindness” or retinal burns, also known as solar retinopathy. This exposure to the light can cause damage or even destroy cells in the retina (the back of the eye) that transmit what you see to the brain.
Where Can You See It? You can see a partial eclipse , where the moon covers only a part of the sun , anywhere in North America ( see “Who can see it?”). To see a total eclipse , where the moon fully covers the sun for a short few minutes, you must be in the path of totality.
It’s been more than three decades since the total solar eclipse of Feb. 26, 1979, which crossed through Washington, Oregon, Idaho, Montana and North Dakota, before heading north to Canada, according to NASA. That’s the last time the contiguous U.S. has seen a total solar eclipse , until the one on Aug. 21, 2017 .
If you are standing in the path of totality , you will be able to see the moon’s shadow come speeding across the land before enveloping you in its darkness.
