Article#131 - Sun and Solar System Planets in Numbers

I was just doing some short surf in the net as I came across this site of a British astronomer, named Robert Simpson (as mentioned in his site). He reconstructed pictures of Sun and Solar System planets, from some numbers, which represent the physical or orbital properties of each bodies, most of them are compared to that of the Earth's.

This is what he said in the post:

Had a bit of fun this weekend creating these oh-so-factual images of the Sun and Planets. There are up to 10 numbers used to create each image - each one giving a characteristic of that particular world, such as the orbital period in years or the mean surface temperature.

These were all made on my iPhone too. Yeah that’s right: I geeked out.

And then... Naah, just go straight to the pictures.

Now let's decipher the numbers and symbols, for Sun.

Hmm, I think that's all. For me, they turned to be pretty well-made. One more advice for the readers: it's better to zoom this page out, the picture will look better when they are small. Just try it. Try it! I say, try it!
