Which planet is known as the Red Planet?

Mars is known as the Red Planet due to its distinctive reddish appearance, which is a result of iron oxide (rust) on its surface. This characteristic gives Mars its name and sets it apart from other planets in the solar system. The coloration is easily observable through telescopes and during certain times of the year when Mars is particularly visible in the night sky. Additionally, Mars has been a focal point for exploration in the search for past or present life, contributing to its prominence in popular culture and scientific discussions.
