A vector is a mathematical construct that has magnitude and direction. The cross product of two vectors is a binary operation in three-dimensional space that results in a third vector that is ...
In the present situation, both Earth and Mars are moving in the same direction around the Sun, but the slower one, Mars, appears to move backwards compared to the faster one, Earth. Just an illusion. The retrograde motion of Mars â like the apparent motion of the slower car on the highway â is nothing more than an illusion.
When a planet goes retrograde, or, appears to be moving backwards through the sky, it often creates a Bizarro World of everything it stands for -- communication planet Mercury in retrograde creates miscommunication, for example. But Pluto's backward shift doesn't makes us confused, it makes us reflective.hen a planet goes retrograde, or, appears to be moving backwards through the sky, it often creates a Bizarro World of everything it stands for -- communication planet Mercury in retrograde creates miscommunication, for example.
