And the Jeddah Astronomical Society revealed in a report that the moon and Mars will be monitored towards the northeastern horizon after midnight, and because the apparent distance between the moon and Mars is wide, they will not appear together in the field of view of the telescope, but this can be done through binoculars.
Observing the brightness of Mars every week is extremely important to see how it will change dramatically between now and next December. These dramatic changes in the brightness of Mars (and its red color) are why the ancients called this planet the god of war. Sometimes the god of war rested and sometimes he became Fierce, these changes are part of the reason why Mars is so amazing to see in the night sky.
To understand why Mars’ brightness varies so much in Earth’s sky, we must realize that Mars is not a very large planet at just 6,790 kilometers in diameter, making it just over half the size of Earth (12,750 kilometers in diameter).
And keep in mind that, unlike Jupiter, Mars is the largest planet in our solar system. Jupiter has a diameter of 140,000 km, more than 20 planets the size of Mars can be aligned in front of Jupiter, so Jupiter always looks bright, because it is very large, but this is not the case for small Mars, whose brightness is related to its proximity or distance from Earth .
Mars revolves around the sun outside of Earth’s orbit and the distance between Earth and Mars changes. Sometimes Earth and Mars are on the same side of the solar system and close together, and sometimes, as was the case for most of 2021, Mars and Earth were on roughly opposite sides of the Earth. The sun is from each other, and thus Mars appears faint.
The reason why the red planet is sometimes bright is because the Earth takes a year to revolve around the sun once, and Mars takes about two years to revolve once.
