It’s a terrestrial planet with a thin atmosphere, featuring surface features like impact craters, volcanoes, valleys, deserts, and polar ice caps. It is one of the most explored planets in our solar system. Mars is the second smallest planet in the Solar System, being larger than only Mercury.

1.1. Basic Facts About Mars

Diameter: Approximately 6,779 kilometers (4,212 miles), roughly half the size of Earth.
Mass: About 11% of Earth’s mass.
Distance from the Sun: Averages about 228 million kilometers (142 million miles).
Orbital Period: One Martian year is 687 Earth days.
Rotation Period: One Martian day (sol) is approximately 24.6 hours.
Atmosphere: Thin, composed primarily of carbon dioxide (96%), with small amounts of argon, nitrogen, and traces of oxygen and water vapor.
Surface Temperature: Ranges from approximately -153°C (-225°F) at the poles in winter to 20°C (68°F) at the equator during summer.
Moons: Two small moons, Phobos and Deimos.

1.2. Why Is Mars Called the Red Planet?

Mars appears red due to the abundance of iron oxide (rust) on its surface. The iron reacts with oxygen, causing the surface and atmosphere to have a reddish hue. This distinctive color has fascinated humans for centuries and is why it is also known as the red planet.
