When the Sun is between a planet and Earth, the planet is said to be in "superior conjunction" if it is an outer planet (beyond Earth's orbit) or in "inferior conjunction" if it is an inner planet (within Earth's orbit). During superior conjunction, the planet is not visible from Earth, while during inferior conjunction, the planet may appear very close to the Sun in the sky.
The planet Mars, which is the fourth planet from the sun, takes 1.88 Earth years to make one full orbit around the sun.
