Saudi news Hours from now, after the suhoor meal, lovers of following astronomical phenomena will be on a date with the conjunction of Mars with the moon, after the red planet got rid of the glare of the sun.
The Astronomical Society in Jeddah said that the planet Mars gradually reappeared in the dawn sky, weeks after its conjunction with the sun on October 8, when it was obscured in the glow of the sun, and since that time its vision has improved with the naked eye and its brightness has gradually increased, reaching the conjunction with the moon before sunrise. This morning, Tuesday, April 26, the sun will be separated by 4 degrees in a phenomenon that you will see with the naked eye.
The Jeddah astronomer explained that observing the brightness of Mars on a weekly basis is extremely important to monitor how it will change dramatically between now and the day of the encounter with Earth in the month of October.
These dramatic changes in Mars’ brightness (and its red color) are why the ancients called this planet the god of war. Sometimes the god of war would rest and sometimes get violent, and these changes are part of the reason why Mars is so amazing to see in the night sky.
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 to each other, and sometimes, as was the case for most of 2021, Mars and Earth were on nearly opposite sides of the Earth. The sun is from each other, and thus Mars appears faint.
The Jeddah astronomer indicates that the reason why the red planet is sometimes bright is that the Earth takes a year to revolve around the sun once, and Mars takes about two years to revolve once, and the encounter of Mars occurs, when the Earth passes between Mars and the sun, every two years and 50 days , so the brightness of Mars wanes and increases in the sky about every two years, but this is not the only cycle of Mars that affects its brightness, there is also a 15-year cycle of bright and faint encounters.
