The history of mars dates back to ancient Egypt in the second millennium. The ancient Egyptian astronomers in the 2nd millennium BCE studied the movement of Mars.
Size and stuff.
The Radius or mass of Mars is 2,106 mi. The weight of Mars is 6.39 × 10^23 kg. The age of Mars is 4.503 billion years. Mars is made up of iron dust and rocks that are the same color. Mars is a red orange-ish color. There has been a discovery of the potentially hazardous radiation to humans. Ice has also been discovered on Mars. A rover on Mars has discovered a stream bed were they believe water once flowed there in ancient times.
Humans have not been to Mars but humans may be expected to be in orbit of Mars and on Mars by the 2030s. Mars has two moons Phobos Deimos. Both moons are potato moons that means that there gravitational pull inst strong enough for them to be a sphere shape. Mars was named after the god of war. Only Mars rovers have landed on Mars. In the winter near the poles the temperature is -195F and in the summer it is 70F. The atmosphere is made of 96% carbon dioxide, 1.9% argon, 1.9% nitrogen, and traces of free oxygen, carbon monoxide, water and methane.
Atmosphere is the gases that surround a planet. Astronomical unit is a measurement form the center of the Earth to the sun that is 149.6 million kilometers. Magnetic field is a region around a magnetic material. Satellite is a a celestial body orbiting the a planet. Evolution is a process were organisms are believed to have developed and diversified from another form. A aurora is a natural electrical phenomenon of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole.
Mars is the 4th planet form the sun and is the second smallest planet in our solar system. Only 18 out of 40 missions to Mars have been successful. Pieces of Mars have landed=on Earth. In the next 20-40 million years Mars will have a ring from Mars’ largest moon Phobos will be torn apart by gravitational forces.
