DEMOGRAPHICS
- Mars is the 2nd smallest planet in our solar system
- 4th planet from the sun
- It is commonly called the red planet because of the red glow it emits
COMPOSITION
- Mars is very similar to earth in its composition
- It has a core of mainly iron and sulfur and a mantle made of silicon
- The crust is made of basalt and just enough iron oxide to make it red.
- Atmosphere: Carbon Dioxide (95.3%) and Nitrogen (2.7%)
- The rest of the atmosphere is a mixture of various gases
Untitled Slide
The red glow of mars comes from the oxidation of iron upon the surface.
SATELLITES
- Mars has 2 natural satellites that orbit it.
- Its two "moons" are also known as Phobos and Deimos
- These moons are actually very small and more closely resemble asteroids
- They are also made of the same material as asteroids.
- (carbonaceous chondrite)

EARTH COMPARISON
- Mars is about half the size of earth (2,106:3,959 radius in miles)
- Mars' gravity is about 37.7% of that of Earth's
- Mars has a rotation of 24 hours and 37 minutes (41 mins longer than Earth)
- Mars has a revolution of 687 Earth days (321.75 day difference)

LIFE ON MARS?
- The existence of life on Mars still remains a mystery.
- However NASA continues to investigate any possibility
- The finding of water and polar ice caps lead to believe it could sustain life
- Although it contains water it couldnt sustain human life due to its atmosphere
- (Lack of breathable air)
FUN FACTS
- Mars' moon Phobos is 14 miles across and Deimos is 8!
- The planet itself is named after the roman god of war.
- Mars is home to the largest volcano in the solar system (Olympus Mons)
- Mars is actually very cold because its atmosphere is not thick enough to trap heat
- During a mars winter almost 20% of the air freezes
