Mars
Mars is the fourth smallest planet in the solar system in terms of distance from the Sun and the second smallest after Mercury. In ancient Roman religion, Mars was called the god of war because they worshiped Mars. Mars is also called the Red Planet because of its red color. This red color is due to the abundance of iron oxide on the surface of Mars. The reddish color of Mars distinguishes it from other celestial bodies visible to the naked eye. Mars is an Earth-like planet with a lighter atmosphere than Earth. On its surface, like the moon of the earth, there are pits formed by the collision of Sahab Saqib or any other celestial body, and on its surface, there are also valleys and deserts like the earth. Like the earth, its poles are covered with ice. The duration of the axial rotation of Mars and the rotation of the seasons is similar to that of the Earth and like the Earth its axis is also inclined which causes the change of seasons. There is a huge volcanic mountain on Mars called Mount Olympus Mons. This mountain is the largest mountain ever discovered on the planets of the solar system. This valley is the largest valley ever discovered on the planets of the solar system. In the northern hemisphere of Mars, there is a smooth basin (geography) called the Borealis Basin. Mars has two moons called Phobos and Demos. These moons are small and random in shape. It is also speculated that they may be small asteroids that have been captured by the gravity of Mars, which is why they are orbiting Mars. Planetary habitation on Mars is being investigated, including traces of life on Mars in the past and the possibility of life on Mars in the present. Future astronomical projects on Mars are planned, including the Mars 2020 and the Exo Mars Rover project. Liquid water does not exist on the surface of Mars due to low atmospheric pressure, although ice is frozen at both poles. There is so much ice at its South Pole that if it were to melt into water, it would cover the entire surface of Mars to a depth of 11 meters (36 feet). In November 2016, NASA discovered a large amount of underground ice in the Ethiopian Planetia region of Mars. Its water volume is estimated to be equal to the water of Lake Superior. Mars can be seen from Earth with the normal human eye.
