The world's last total solar eclipse occurred in August 2017. Millions of Americans stopped what they did to observe the eclipse that passed over parts of the entire United States.
A total solar eclipse happens when the sun, moon and earth match perfectly. The next total eclipse will happen on July 2.
However, the total eclipse can only be seen in a few places in the world. This year, the overall route will pass over areas in Chile and Argentina. The American space organization NASA says the sun will be completely hidden by the moon for up to four minutes and 33 seconds during this eclipse.
The upcoming event has led people from all over the world to plan to travel to the Northern Coquimbo region of Chile where the total eclipse is expected to be visible . Local officials say they expect more than 400,000 visitors to the area.
