Rover's Planet is a term used to refer to MARS, the fourth planet from the Sun. MARS is the only planet in our Solar System that is home to rovers, which are robotic vehicles designed to explore the surface of the planet. The rovers have been sent to MARS by various space agencies around the world in order to study the planet's environment and search for signs of life. Rover's Planet is also known as the Red Planet due to its reddish hue, which is caused by iron oxide on its surface.
