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.
It takes Mars about 687 Earth days (1.882 Earth years) to orbit the  Sun.    The orbital path of Mars is about twice that of Earth. Mars orbits  about 227 million kil â¦ ometers away from the Sun. The planet travels  a distance of approximately 1.43 billion kilometers (888 million  miles) in 686.971 Earth days.It takes 1.88 years for mars to make one revolution around the sun.
