As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.

Mars' Calendar. Time on Mars is easily divided into days based on its rotation rate and years based on its orbit. Sols, or Martian solar days, are only 39 minutes and 35 seconds longer than Earth days, and there are 668 sols (687 Earth days) in a Martian year.
11 paź 2024 · On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation.
29 lip 2021 · Learn about the characteristics of the Earth and Mars, two planets in our Solar System. Scientists have studied Mars by peering through telescopes, sending robotic spacecraft to orbit the planet, and placing landers and robotic rovers on its surface.
Mars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light. Despite being inhospitable to humans, robotic explorers – like NASA's new Perseverance rover – are serving as pathfinders to eventually get humans to the surface of the Red Planet.
