Which planet is known as the Red Planet?

Mars is known as the Red Planet due to its reddish appearance in the night sky, which is caused by iron oxide, commonly known as rust, on its surface. The presence of iron-rich minerals gives Mars its distinctive color, setting it apart from other terrestrial planets in our solar system. This iconic coloration has made Mars a focal point in both scientific study and popular culture, often associated with the search for extraterrestrial life and exploration.

In contrast, Jupiter is a gas giant characterized by its massive size and striped appearance due to its atmospheric bands. Venus, often referred to as Earth's "sister planet," has a thick, toxic atmosphere and is known more for its brightness and cloud cover than any coloration related to "red." Saturn, famous for its prominent ring system, is also not associated with a red hue in the same way Mars is. Each planet has unique features, but the specific iron oxide presence on Mars solidifies its recognition as the Red Planet.
