What Color Is Mars, And Why?
Mars is one of the most famous planets in the Solar System, and part of this is due to its iconic color. Despite being such a minuscule speck in the grand scheme of outer space, our own Solar System is a pretty fascinating place. It's home to eight unique planets, each of which has its own unique characteristics. Jupiter is a massive gas giant, Saturn has gorgeous rings, and Earth is the only known planet with life.

Out of all the planets in the Solar System, Mars is one of the most fascinating — primarily because of humans' fascination with finding life there. Research has shown evidence of water and carbon molecules on Mars, reinforcing the idea that life may have once existed there. It's a mystery that may take years to fully explain, but even so, it remains one of the biggest topics in all of space exploration.

So Mars is red. That's easy enough to explain. But why is Mars red? It all has to do with the planet's composition. Many of the rocks on Mars are rich in iron. Just like when iron sits outside for too long on Earth and forms rust from iron oxidization, the
