Question
why is  mars known as the red planet

Answer
Because it looks fairly reddish, as seen from Earth.  It is colored red because it has lots of iron in it.  Have you ever noticed how rust is sort of red in color?  The surface of Mars is very similar, chemically, to rust.  Therefore, just like rust, it has sort of a red color to it.

Expertise

I am not a professional astronomer by any means, but astronomy has been an interest of mine since childhood, and I am well-informed on the subject. If unable to answer someone`s question personally, I will know how to quickly find the answer online, because I keep myself informed about developments in the field and I know where to look for information.

Experience

I worked in an observatory for awhile at one point, doing various interesting things with a computer.
