Mars, often called the Red Planet, is the fourth planet from the Sun in our solar system. While smaller than Earth, it still boasts impressive proportions.

  • Diameter: Mars measures about 6,779 kilometers (4,212 miles) across at its equator, roughly half the size of Earth.
  • Mass: The planet's mass is approximately 6.39 × 10^23 kilograms, about 10.7% of Earth's mass.
  • Surface Area: Mars covers 144.8 million square kilometers, equivalent to all of Earth's continents combined.
  • Volume: Its volume is 1.63 × 10^11 cubic kilometers, about 15% of Earth's volume.
  • Gravity: Due to its smaller size and mass, Mars' surface gravity is only 38% of Earth's.

Despite its smaller stature, Mars' size allows it to retain an atmosphere and host massive geological features, including Olympus Mons, the largest known volcano in the solar system.

Would you like me to elaborate on any specific aspect of Mars' size or its implications for the planet's characteristics?
