Mars looks red because it's covered in rusty dust! πβ¨ Just like how an old bike left outside turns orange, Mars has lots of iron (like in your toys) that got rusty over time.
The wind blows this dust all around, making the whole planet look red! π
Mars is red because its surface is full of iron oxideβthe same thing that makes rust on Earth! π΄ The iron in Mars' rocks reacted with oxygen (long ago when Mars had water) and turned into rust.
Strong winds spread this rusty dust across the planet, giving it a reddish color. Scientists call Mars the 'Red Planet' because of this!
Mars appears red due to iron(III) oxide (rust) covering its surface. Billions of years ago, Mars had liquid water and a thicker atmosphere, allowing iron in the soil to oxidize (rust). Over time, volcanic activity and meteorite impacts ground the rusty rocks into fine dust.
Today, global dust storms spread this iron-rich dust across the planet, reflecting sunlight in a way that makes Mars look reddish-orange. This is why telescopes and spacecraft show Mars as a 'Red Planet.'
Fun fact: Mars' two moons, Phobos and Deimos, are likely captured asteroids! πΈ
