Mars est la planète extérieure la plus proche de la Terre. La distance qui sépare les deux planètes est la plus faible lorsque Mars est en opposition, c'est-à-dire lorsque la Terre s'intercale entre Mars et le Soleil.
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 Perseverance rover – are serving as pathfinders to eventually get humans to the surface of the Red Planet.
Mars est la quatrième planète du Système solaire, en comptant à partir du Soleil. Les scientifiques pensent que toutes les planètes ont été créées il y a un peu plus de 4,5 milliards d'années.
Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.
2 juil. 2024 · L'inclinaison axiale de Mars est très similaire à celle de la Terre : la planète rouge est inclinée à 25,2°, alors que l'inclinaison axiale de la Terre est d'environ 23,5°. Pour cette raison, Mars a quatre saisons distinctes : le printemps, l'été, l'automne et l'hiver.

Explore the surface of Mars with Google Maps. Zoom, rotate and search for landmarks and features on the red planet.
Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
30 juil. 2020 · The Mars 2020 Perseverance Rover searches for signs of ancient microbial life, to advance NASA's quest to explore the past habitability of Mars. The rover is collecting core samples of Martian rock and soil (broken rock and soil), for potential pickup by a future mission that would bring them to Earth for detailed study.
Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.
