In the discussion you are asked is there a Lagrangian points?
The answer is no.
But this is pretty important question for everyone who is familiar with orbital mechanics, so let's describe it in more detail.
Lagrangian point, briefly, is a point where two nearest celestial body affect on the ship with the equal gravity force.
In order for this phenomenon to be possible - ships should be affected by gravity from more than one nearest celestial bodies (planets or moons), like in the real world.
But in the Celestial Command, only one nearest planet affect the ship. But why?
There is two reason.
First one, optimization. Gravity calculation to one planet gives better performance then to all planets in the system. But this is not important reason.
Another more important reason is tidal forces.
Let me explain. As we know, the closer object is to the planet - the more powerful gravity affect it. For example.
The moon is pulling point A stronger than point B and this is called tidal force. And that's why tides exists
But lets imagine a ship on the Earth's orbit. When it passes above point A it will be attracted by the Moon and its orbit will be deformed so much so stable orbiting will be impossible.
Actually, the same phenomenon exist in the real life. But it is relative to the distances between celestial bodies. For example orbit height of the International Space Station is 420 km. And distance to the Moon is 380 000 km. So while ISS rotating around the Earth, distance between ISS and Moon changes only slghtly, so orbit is not deformed that much.
But in the Celestial Command distances are much shorter thus said, orbits are deforming quite a bit..
So this is why we decided to simplify the orbital mechanics in Celestial Command.
