Average distance from the Sun: 141,700,000 mi.
Diameter of the planet: 4194 mi.

Mars, the fourth planet from our sun, known as The Red Planet.
The Romans named it after their god of war.
The mass of Mars is 1.416 trillion trillion pounds.
One day on Mars is 24.6 hours long.
The most common gas in Martian atmosphere is Carbon Dioxide.
At any given point, Mars is between 128.4 and 154.9 million miles away from the sun.
A year on Mars is nearly twice as long as an Earth year--1.88 Earth years to be precise.
The average temperature on Mars is -9.4 degrees farenheit.
Mars has two moons: Phobos and Deimos.
Phobos circles Mars at 5,860 miles, Deimos at 14,690 miles.
Phobos is the larger and innermost of Mars' two moons.
Deimos is the smaller and outermost of Mars' two moons.
It is the smallest known moon in the solar system, its diameter is 12 kilometers.
Phobos and Deimos are widely believed to be captured asteroids from Jupiter.
There is some speculation that they originated in the outer solar system rather than in the main asteroid belt.
It is predicted that the two moons will crash into each other in 30 million years.
Mars has an atmosphere, it is almost all carbon dioxide (95%).
Its atmosphere is less than a hundredth as dense as the atmosphere of Earth.
Because the atmosphere is so thin, it responds to seasonal changes much more quickly.
The poles on Mars have (water) ice caps.
When it's warm in one hemisphere, the ice cap warms up and evaporates and mixes with the carbon dioxide in the atmosphere.
In the other hemisphere, temperatures drop to -190 degrees Farenheit and the ice cap freezes.
When the seasons switch and the carbon dioxide freeze-out occurs, the atmospheric rush is reversed.
These high-altitude shifts trigger events that can explode into planet shrouding dust storms.
Many people claim that Mars could support life, and many people believe it does.
Various hills and valleys on the surface of Mars are supposedly evidence of a bygone Martian civilization.
