KOMPAS.com – Mars has the pseudonym as a red planet. This pseudonym is given because the planet often appears in the sky as an orange red "star".
Beyond that, after visiting several spacecraft on Mars, we know that the appearance of the planet is indeed red.
Then, where does the reddish color come from?
Summarizing the official website of the European Space Agency (ESA), the red color is caused by rust or oxide particles in Martian rocks.

In addition, the sky of Mars often appears bright pink or orange. This is due to the fact that the dust of the coral particles on its surface is flowing into the fine atmosphere of Mars.
Two because this causes the color of Mars to appear from the Earth to be orange red.
Where does the rust come from?
As already explained, the red color of Mars is due to rust particles. But, where does the particle come from?
Reporting by Space.com, all this began 4.5 billion years ago. When the solar system is formed, many planets are made of iron elements.
If on Earth, the element then sinks into the core of the planet and melts. But, according to NASA scientists, this is not the case on Mars.
The smallest size of Mars from Earth and its weaker gravity allows the planet not to sink the iron.
As a result, there is iron that remains abundant in the upper layers of the planet.
The next story is a kind of iron erosion on Mars surface that is progressive and destructive. This time is because there is an exposure to oxygen in the iron on the surface of Mars.
Exposure to oxygen generates iron oxide compounds or rust particles. This makes the planet Mars reddish.
