Red Planet

The "Red Planet" refers to Mars, the fourth planet from the Sun in our solar system. It is known for its reddish appearance, which comes from iron oxide, or rust, on its surface. Mars has unique features like the largest volcano, Olympus Mons, and a deep canyon, Valles Marineris. Scientists are particularly interested in Mars because of evidence that it once had water and possibly supported life. Ongoing exploration, including rovers and planned missions, aims to learn more about its geology, atmosphere, and potential for future human habitation.
