Mars is the fourth planet in our solar system, located between Earth and Jupiter. It is often referred to as the "Red Planet" due to its reddish appearance.
Mars has a day length that is very similar to Earth's, with a day lasting approximately 24 hours and 37 minutes.
The gravity on Mars is much weaker compared to Earth. The gravitational acceleration on Mars is approximately 3.71 meters per second squared (m/s²), which is about 38% of Earth's gravity.
Mars experiences extreme temperature variations. On average, temperatures can range from -195 degrees Fahrenheit (-125 degrees Celsius) at the poles to a high of 70 degrees Fahrenheit (20 degrees Celsius) at the equator during summer.
Mars also features the largest canyon in the solar system called Valles Marineris. It stretches approximately 2,500 miles (4,000 kilometers) long and is up to 4.3 miles (7 kilometers) deep.
Mars is home to the largest volcano in the solar system called Olympus Mons. It is about 13.6 miles (22 kilometers) high, making it nearly three times the height of Mount Everest.
Mars has two moons named Phobos and Deimos. They are irregularly shaped and are believed to be captured asteroids.
Mars has a thin atmosphere composed mostly of carbon dioxide (95%), with traces of nitrogen and argon. It is about 100 times less dense than Earth's atmosphere.
Multiple rovers have been sent to Mars to study its surface and search for signs of past or present life. Notable rovers include the Sojourner, Spirit, Opportunity, Curiosity, and the most recent Perseverance rover.
Mars is a primary target for future human exploration and colonization efforts. Space agencies and private companies are actively planning missions to send humans to Mars within the next few decades.
