Mars

Mars is the fourth planet from the Sun and the seventh largest in the Solar System. A cold, dusty desert world with a thin atmosphere (mostly CO₂), the planet features extinct volcanoes, deep canyons, polar ice caps, and seasons. Mars has two small moons (Phobos and Deimos), a day just over 24 hours long, and a year lasting about 687 Earth days. It is a prime focus of robotic exploration and studies about past water and habitability.

The crescent Moon, Venus, and Jupiter all appeared together in the early morning hours of April 23rd. Some locations on Earth were able to witness a rare double conjunction eclipse, where the Moon occulted both Jupiter and Venus at the same time. The next double conjunction eclipse will involve Mercury and Mars and will occur on February 13, 2056.
