Mercury, Venus and Jupiter are three of the brightest planets in the Solar System.
These three planets revolve around the Sun with different periods. When the three
planets move to the same side of the Sun (See diagram 1), they can be observed at
the same time from the Earth to form the astronomical phenomenon known as the
"Parade of the three planets". Diagram 1 : Mercury, Venus and Jupiter move to the same side of the Sun to form the astronomical phenomenon known as the "Parade of the three planets"
