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 occurs when the sun, moon and earth are perfectly aligned. The next total solar eclipse will take place on July 2.
However, the total eclipse can only be seen in a few places in the world. This year, the whole road will pass over areas in Chile and Argentina. The American space carrier 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 Chile's northern Coquimbo region where the total solar eclipse is expected to be visible . Local officials say they expect more than 400,000 visitors to come to the area.
