Two planets on the beach

Among the general public, there’s remarkably little awareness of the solar system, our immediate environment, our neighbourhood. Many people simply don’t know the difference between the solar system, the galaxy and the universe. Even Dutch national quality newspaper the Volkskrant once wrote that Jupiter is the largest planet in the universe (I’ll never forgive them).

Naming the eight planets in the right order is a basic skill that few people posses. Knowledge about the size and mutual distances of these celestial bodies is also very limited.

For some reason, many people think that Mars is bigger than the Earth. Perhaps that has something to do with its bloody history as a Roman war god. Even though we now know that this red color has more to do with rust than with blood.

In reality, our homeworld is about twice as big as Mars. The Earth has a diameter of 12,742 kilometers; our neighbor planet measures only 6,779 kilometers. These are distances that not everyone covers daily, so I have reduced the scale, in this 3ds Max rendering, to something more imaginable: two beach balls.

The planets Earth and Mars represented by two beach balls in the sand, on the right scale ratio to each other.


With this image , I hope to iron out a frequent misunderstanding. I’m talking about the idea that Mars is a nice backup planet, and that we can all move there if the situation on Earth becomes untenable.

Mars is a nice piece of real estate, with deep valleys, high mountains, massive ice caps and cool craters. But if we go there all together, it will be a bit tight. Not even mentioning unpleasant aspects like the low temperatures and the thin and toxic atmosphere.


I would really like to see people go to Mars to explore the planet and try to build a society there. In case another huge meteor strikes Earth, it is good to know there is a branch of civilization elsewhere.

And I also believe that it is possible to terraform Mars; in simple terms: to provide it with a more friendly climate and atmosphere. But terraforming will be an ultra-long term project and it does not make the planet bigger. It remains a relatively tiny world.

No, let’s be a bit careful with that beach ball on the left.

My work explores the border regions of photography, painting and computer visuals. With my company 3Develop I do work in commission but I use the same techniques, skills and software to make free work. I am originally an architect and I live in Rotterdam; for that reason the architecture of that city is a major (but not the only) source of inspiration. But also travel to countries like Iceland and Britain, or walks in the Netherlands, provide much material. Seeing and showing quality and beauty, that is what my work is about.
