Mars
Explanation
Mars is widely known as the 'Red Planet' of our solar system. The distinctive reddish appearance is due to the widespread presence of iron oxide (rust) on its surface, in its soil, and rocks. When viewed from Earth, even with the naked eye, Mars has a noticeable red tint. It is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury.
