Jul 11, 2022 · Mars, the fourth planet from the sun is famed for its rusty red appearance. Here we explore the Red Planet in more detail.
It is classified as a terrestrial planet and is the second smallest of the Solar System's planets with a diameter of 6,779 km (4,212 mi). In terms of orbital motion, a Martian solar day is equal to 24.5 hours, and a Martian solar year is equal to 1.88 Earth years (687 Earth days).
The red planet Mars, named for the Roman god of war, has long been an omen in the night sky. And in its own way, the planet’s rusty red surface tells a story of destruction.
The Red Planet is actually many colors. At the surface, we see colors such as brown, gold, and tan. The reason Mars looks reddish is due to oxidization – or rusting – of iron in the rocks, regolith (Martian “soil”), and dust of Mars. This dust gets kicked up into the atmosphere and from a distance makes the planet appear mostly red.
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.
3 days ago · Mars is the fourth planet in the solar system in order of distance from the Sun and the seventh in size and mass. It is a periodically conspicuous reddish object in the night sky. There are intriguing clues that billions of years ago Mars was even more Earth-like than today.

Feb 20, 2018 · But evidence suggests that in the early history of our solar system, Mars had an ocean’s worth of water. NASA’s James Webb Space Telescope will study Mars to learn more about the planet’s transition from wet to dry, and what that means about its past and present habitability.
Highlights. Mars once had liquid water on its surface and could have supported life. Scientists are uncovering how Mars transformed into the cold, dry desert world it is today. We explore Mars to understand the planet's history and look for evidence of past or even present life.
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 currently has two rovers ( Curiosity and Perseverance ), one lander ( InSight ), and one helicopter ( Ingenuity ) exploring the surface of Mars.
