Mars is the fourth planet from the Sun in our solar system.
It's often referred to as the "Red Planet" due to its reddish appearance, caused by iron oxide (rust) on its surface.
Mars has a thin atmosphere primarily composed of carbon dioxide.
The planet has distinctive features like the largest volcano in the solar system, Olympus Mons, and the massive canyon system Valles Marineris.
Scientists have been studying Mars for its potential to harbor past or present life and as a target for future human exploration.
