Watching Kurtjmac's Minecraft Far Lands Or Burst #070, where Kurt talks about Lagrange Points and the cycles of a moon, I started thinking about how the Minecraft Solar System actually looks like.

What I've come up with is this.

We all know that our Moon's cycle is due to the Earths rotation, both around its own axis and around the Sun, as well as due to the Moons own rotation around the Earth and its own axis.
In order for the Minecraft Moon to be allways in a "full appearance", it needs to always reside at the opposite side of the sun, with the Earth in between. This would show a full moon, while it would retain its route across the sky, caused by the Earth's rotation. Thus, as the Minecraft Eath would travel around the Sun, the Moon would always be in the dark side of the Earth.

The seasons, since there always seems to be only one season, despite the different biomes, are caused by two things. One is the tilt of the Earth's axis. For one and only one season to occur, the first thing needed is a non-tilted axis. This means that the Minecraft Earth would always rotate around its direct center in a straight way, unlike our Earth, which is tilted.
The second thing is the rotation of the Minecraft Earth around its star. For only one season to occur, the Earth has to rotate around the Sun in a perfect circle. This way, the Sun's travel through the sky would never change and would always be in one direction, without any other movement or change.

Thus, we have a moon that doesn't rotate around its planet and always stays at one side of it (in real life, this would cause it to crash into the planet). The planet would have no tilted axis and would travel in a perfect circle around its star.

The only thing we can only guess about is the size of each body and the distances relative to each other. For all we know, the body we call the moon could actually be a planet of the same size as the earth.

But that's my thinking. What do you think about this?
