Which planet is known as the Red Planet?

Mars is known as the Red Planet due to its characteristic reddish appearance, which is primarily caused by iron oxide, commonly known as rust, on its surface. This distinctive color can be observed even from Earth, which is why Mars has been associated with the description of "red." The planet's surface is dotted with canyons, volcanoes, and polar ice caps, contributing to its varied landscape. This color has also played a significant role in various cultural aspects, linking Mars to themes of war and aggression in mythology and art. Mars holds a particular fascination for scientists due to the possibility of past water existence and its potential for hosting life.
