Answer 1

Mars is second smallest planet in our solar system.Mars was named after the Roman God of war , because of its blood colour.The planet looks very rusty red because of its surface covered with iron rich soil and rock.There are no seas on Mars, and it is very cold.Mars has two tiny moons , Deimos and Phobos , which are not round like our Moon. They look more like baked potatoes.They might have been asteroids [ space rocks] that Mars captured with its gravity.
Phobos is about 15 km long ,whereas , Deimos is about 27 km long.
Amazing fact about Mars :  There's a record breaking Volcano on Mars.Olympus Mons is about 600 km across and towers over 25 km high.It's the Solar System's biggest volcano.Long ago,its spurted out running rivers of black lava.
The south pole of Mars is mostly dry ice , which is  frozen Carbon dioxide gas.At the north pole there may be frozen water,mixed with frozen Carbon dioxide .There may be frozen water underground on Mars,too.
Long ago,Mars had flowing rivers of water , so there could have been life once , and there may be fossils buried underground.

Answer 2

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System (in adherence with the IAU's controversial 2006 definition of planet), being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet". The latter refers to the effect of the iron oxide prevalent on Mars's surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye.Mars is a terrestrial planet with a thin atmosphere, with surface features reminiscent of the impact craters of the Moon and the valleys, deserts and polar ice caps of Earth.
