Which planet is known as the "Red Planet"?

Mars is known as the "Red Planet" due to its reddish appearance, which is a result of iron oxide, commonly known as rust, on its surface. This distinctive color makes Mars stand out in the night sky and has led to its nickname. The reddish hue has fascinated observers for centuries, prompting various cultures to associate it with war and aggression in mythology. Unlike Venus, which appears bright white due to its thick cloud cover, or Earth, known for its blue oceans and green landmasses, Mars’ surface features, such as its dust and rocks, contribute to its unmistakable red color. Jupiter, being a gas giant, does not have a solid surface and is characterized by its bands of color, but it does not reflect the same distinct red hue that Mars does. Thus, Mars' composition and atmospheric conditions are key factors in its identification as the "Red Planet."
