It is the first total solar eclipse to pass over the continental United States in 99 years.
So many people are looking forward to witnessing this incredible moment that experts are saying this special solar eclipse could be the most viewed celestial event in history!
About 12 million people live in its main path and about 88 million more Americans live within 200 miles of the eclipse's trajectory.
If you live this close to the "path of totality," it just might be worth hoping in your car for an eclipse road trip.
If you're an enthusiastic sky watcher, or if you've got little ones, why not pack up your tent and make an adventure out of it!
NASA officials explain that a single spot on Earth will only get to witness a solar eclipse every 375 years. That makes this a once-in-a-lifetime chance!
