Today we are going to talk about some unknown facts about our very next planet Mars.
Before we start, if you didn’t see our previous parts then you can read them from here.
So, let’s start-
Distance from the sun?
Colour of Mars:
The surface of this planet is distinguished reddish colour, quite similar to the colour of rust; and the reason may actually be quite similar to why rust looks as it does. The largest factor behind Mars’ red hue is the high levels of iron oxide found in its surface material.
But how so much of the iron becomes oxidized in an atmosphere, comprised of only 0.146% oxygen?
Well, scientists point to several theories, including rainstorms in Mars’ younger years, a billion years of sunlight breaking down carbon dioxide into oxidants or heavy dust storms breaking down quartz crystals to expose oxygen-rich surfaces.
Size of Mars:
Mars measures up around 21344 km in circumference making it significantly smaller than the earth. Where Earth’s circumference is around 40070 km. For your better knowledge, around six Mars is could fit inside the earth.
Mars vs Earth:
- Mars is about 15% of the Earth’s volume yet only 11% of Earth’s mass. That means it is not only smaller than the earth but also denser than the earth.
- Despite that Mars is smaller than Earth, the two planets actually have roughly the same amount of land. This is because around 2/3 of the earth is covered in oceans.
Gravity:
Because of Mars’ diminished size, the gravity on it is less than 40% of the earth.
So, if you think that your weight is too much then that’s not your fault, you are just on the wrong planet.(trying to be funny😅😅)
Naming the planet:
We know it more commonly by the same name as the Roman God of War, Mars has several different names. Like the Romans, Greece associated the red planet with their God of War, Ares while East Asian cultures consider it the “fire star”. Mars was first observed via telescope by none other than Galileo in 1609 or 1610.
