Facts about Mars

Mars and Earth have approximately the same landmass:
Even though Mars has only has 15% of the Earth’s volume and just over 10% of the Earth’s mass, around two thirds of the Earth’s surface is covered in water. Martian surface gravity is only 37% of the Earth’s

Mars is home to the tallest mountain in the solar system.
Olympus Mons, a shield volcano, is 21km high and 600km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so recent many scientists believe it could still be active.

Mars has the largest dust storms in the solar system:
They can last for months and cover the entire planet. The seasons are extreme because of it’s elliptical (oval-shape(d) orbital path around the Sun is more elongated than most other planets in the solar system.

Pieces of Mars have fallen to Earth:
Scientists have found tiny traces of Martian atmosphere within meteorites violently ejected from Mars, then orbiting the solar system amongst galactic debris for millions of years, before crash landing on Earth. This allowed scientists to begin studying Mars prior to launching space missions.
