If you watched the event from Jupiter, you would see the three moons pass directly in front of the Sun.
Here on Earth, our Moon is just big enough to completely blot out the Sun for minutes at a time during a total eclipse.
The Earth, however, only has one lunar companion and Jupiter is home to an incredible total of 79 known moons.
But even with so many satellites, NASA said the appearance of three eclipses at once is an incredibly rare occurrence.
The US space agency said: “Why is this triple eclipse so unique? Io, Ganymede, and Callisto orbit Jupiter at different rates.
