​The Red plant

​

Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past. ​

What are 5 interesting facts about Mars? ​

​Mars is also known as the Red Planet. This is because Mars is covered in soil, rock, and dust made from iron oxide which gives the surface a rusty red color. 

2. Mars is named after the Roman god of war. 

3. Mars has 2 moons called Deimos and Phobos. They are named after the two horses that pull the Roman god of war, Mars’, chariot. They may be asteroids captured by Mars’ gravity. 

4. Mars is the 4th planet from the sun. It is 227,936,637 km (141 million miles) away from the sun. It would take 300 days (around 8 months) to get there from Earth. 

5. Mars is smaller than Earth with a diameter of 4217 miles. This makes it the second smallest planet in our solar system.

​Mariner 4, which flew by Mars on July 14, 1965, found that Mars has an atmospheric pressure of only 1 to 2 percent of the Earth's. Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. But on Mars, carbon dioxide is 96% of the air! Meanwhile, Mars has almost no oxygen; it's only one-tenth of one percent of the air, not nearly enough for humans to survive. If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant.

​Why mars is red?

So where does that redness come from? Well, a lot of rocks on Mars are full of iron, and when they're exposed to the great outdoors, they 'oxidize' and turn reddish - the same way an old bike left out in the yard gets all rusty.

Mars is known as the Red Planet because the iron oxide chemicals in its soil looks like rust. Mars is named for the ancient Roman god of war. The Greeks called the planet Ares (pronounced Air-EEZ). The Romans and Greeks associated the planet with war because its color resembles the color of blood.

​While the red planet's thin atmosphere and bitter cold temperatures keep these frozen clouds from ever falling in the form of rain and snow we see here on Earth, there is actually a type of precipitation on Mars. "This precipitation most likely takes the form of frost," NASA explains. 

​

​With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry.
