Mars is a cold desert world with a thin atmosphere.
Mars is about half the size of Earth. It is 227.9 million kilometers (141.6 million miles) away from the Sun. A year on Mars (one full orbit around the Sun) takes 687 Earth days, almost twice as long as Earth year. A day on Mars (one full spin on its axis) is about 24.6 hours, slightly longer than an Earth day.
Mars has mountains, valleys, and canyons. It has the largest volcano in the Solar System, Olympus Mons, which is about three times taller than Mount Everest. Mars also has Valles Marineris, a canyon system that is over 4000 km (2500 miles) long. This is ten times longer than the Grand Canyon on Earth. Mars also has polar ice caps made of water and carbon dioxide.
Mars has a thin atmosphere made mostly of carbon dioxide, with very little oxygen. The temperatures on Mars are much colder than on Earth, averaging around -63°C (-81°F). Because of its thin air, Mars experiences strong dust storms that can last for months and cover the entire planet.
Scientists have found evidence that Mars once had rivers, lakes, and even oceans. Today, most of Mars' water is frozen in its polar ice caps or hidden beneath the surface.
Mars also has two small moons, Phobos, and Deimos. They are much smaller than Earth's Moon and have irregular shapes. Scientists think they might be captured asteroids or might be formed during the collision.
Mars has been explored by many spacecraft, including orbiters, landers, and rovers. NASA's rovers Curiosity and Perseverance are studying the surface and looking for signs of past life. Other countries like China, India, and the UAE have also sent missions to Mars.
Scientists are studying if humans could live on Mars in the future. The main challenges are the thin atmosphere, extreme cold, and lack of liquid water. NASA and companies like SpaceX are working on plans to send astronauts to Mars.
Mars remains one of the most exciting planets for exploration. Scientists continue to study it to learn more about its past and whether life ever existed there.
