"Mars".

This is Mars. Mars is the second smallest planet in the solar system after Mercury. Mars looks reddish because it has an excess of iron oxide on its surface, and this makes it one of the most visible cosmic objects to the naked eye.
So this planet is also known as the red planet. This Mars is but a rocky planet. Since the rotations of Mars and Earth are similar, the periods and seasons of the two planets are similar to those of Earth.
The number of natural satellites of Mars is again of two types such as Phobos and Dimos. However, these two satellites tend to be very small in size and look irregular.
However, it is estimated that these two asteroids are stuck in the gravitational pull of Mars. Scientists are still researching whether Mars is suitable for habitation at all.
The radius of Mars is half of our Earth and its mass is about 1/10 of the Earth. Although Mars is larger than Mercury, Mercury has a higher density. As a result, the gravitational force on the surface of Mercury is relatively high.
Scientists have observed from many observations and meteorites that the surface of Mars is composed mainly of basalt. Mars has no internal magnetic force of its own. But yes, scientists have observed that magnets have been found in some parts of the Earth's crust.
The core of Mars is made up of iron sulfide, most of which is liquid. Surrounding the center is a mantle made up of silicate that plays a major role in the formation of planetary rock formations and volcanic structures.
But now it is known that this mantle is inactive. At present, it is not possible to find liquid water on Mars due to the extremely low atmospheric pressure.
But there is so much ice that the two poles of the planet are completely covered in ice. There is so much ice on this planet that if completely melted, the whole planet would be submerged.
