Which planet is known as the Red Planet?

Mars is known as the Red Planet primarily due to its distinctive reddish appearance, which is caused by iron oxide, commonly known as rust, on its surface. This characteristic has made Mars a subject of fascination in both scientific study and popular culture. It is the fourth planet from the Sun in our solar system, and its reddish color can often be observed from Earth with the naked eye, earning it the nickname 'Red Planet'. The name Mars itself is derived from the Roman god of war, which is fitting given its striking and vivid color.

In contrasting Mars with the other planets mentioned, Venus, Earth, and Jupiter do not share this reddish hue. Venus appears bright yellowish-white due to its thick cloud cover, Earth is known for its blue oceans and green landscapes, and Jupiter is a gas giant characterized by its bands of color, primarily browns and yellows, along with its Great Red Spot. This further reinforces why Mars is uniquely recognized as the Red Planet in our solar system.
