On December 7, 2022, our planet Earth passed between Mars and the sun, bringing Mars to its once-in-two-years opposition in our sky. Mars was at its closest and brightest for this two-year period, and it was opposite the sun. A full moon is also opposite the sun. So, on December 7, the sun, the Earth, the moon and Mars were aligned. And the alignment was so precise that – as viewed from some parts of Earth – the moon passed in front of Mars! Elsewhere, red Mars was widely seen near the full moon in the sky on the night of December 7-8. Heartfelt thanks to all who submitted photos to EarthSky Community Photos. We love you all! A few favs on this page … and more moon and Mars photos here.
