Planet Positioning

Introduction
All of the planets are not equal: some are bigger, some smaller, and some are closer or farther from the Sun than others. But what does it all mean?
 * Planets can be between Pos 1 and 15.

Size of your planet
The bigger your planet is, the better your metal and crystal mines will work, meaning they will produce more for the same amount of energy.

Size is affected by Sun distance as well. The middle planets of the galaxy are usually bigger than the planets placed on the front or rear of the galaxy. For instance, it is probable that a planet placed into the 7 position will be bigger than a planet placed into position 1.

The starter planets are all the same size, so this point is only useful after you started colonising.

Distance from the Sun
You planet can be far or close to the Sun, and it is more impactful than you might think:

The planets closer to the Sun produce more energy, as they receive more light, but produce way less Deuterium, a really rare material, produced only in small quantities.

The further you are from your Sun, the more Deuterium you will be able to produce, but the less energy you will be able to produce: the further you are, the less light you receive, so your Solar Power Plant will produce less.
