Rust within the soil creates the Pink Planet’s signature colour.

Dimension: Mars is about 4,212 miles (6,779 kilometers) in diameter.

Distance from the Solar: Mars is the fourth planet from the Solar and orbits roughly 142 million miles (229 million km) away.Orbit across the Solar: It takes 687 Earth days for the Pink Planet to go across the Solar one time.Rotation: Mars spins on its axis at about the identical velocity as Earth does. It takes 24 hours and 37 minutes (about 1 Earth day) for Mars to rotate one time.

Floor: There are many dry channels on Mars, and so they appear like Earth’s river channels. Most scientists consider water as soon as flowed on the martian floor, however new research counsel there nonetheless could also be water in some locations at and beneath the floor.

Mars has the biggest canyon (Valles Marineris), and the best volcano (Olympus Mons) within the solar system.

If Valles Marineris have been on Earth, it will span the USA, from New York on the East Coast to California on the West Coast. The canyon is about 1,300 miles (2,100 km) lengthy, 300 miles (500 km) large, and about 5 miles (8 km) deep.

Olympus Mons is about thrice increased than Mount Everest. It rises above the Martian floor 14 miles (22 km). This large volcano’s base is the scale of the state of Missouri.

The planet’s reddish colour is attributable to rust (iron oxide) within the soil.

The polar ice caps on Mars are product of frozen carbon dioxide, or dry ice, plus a seasonal coating of water ice.

Environment: The martian ambiance may be very skinny and product of carbon dioxide (95 %), nitrogen (3 %), argon and different gases (1 %).

Temperature: The bottom floor temperature on Mars is –190° F (–123° C), whereas the most popular temperature is 90° F (32° C).Escape velocity: To flee the gravity of Mars, you must journey 11,200 miles (18,000 km) per hour, in comparison with 25,000 miles (40,200 km) per hour obligatory to flee Earth’s gravity.Different data: As a result of the Pink Planet’s colour reminded historical astronomers of blood, they named the planet after their gods of struggle. Mars was the Roman god of struggle, whereas Ares was the Greek model. The planet’s two moons even have names that relate to struggle. Phobos means “concern,” and Deimos means “panic.” Phobos is about 17 miles (27 km) in diameter and Deimos is about 9 miles (14 km).
