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.
Mars usually appears distinctly yellow, orange, or red. When farthest away from Earth, it is more than seven times farther away than when it is closest. Mars is usually close enough for particularly good viewing once or twice at 15-year or 17-year intervals. [196]

17 wrz 2024 · What does Mars look like? This infographic uses composite orbiter images and an outline of the United States to show the scale of the Valles Marineris (a canyon system more than 2,000 miles long!). Swipe left and right to see how big this canyon system is compared to the United States.
