Fleets located on satellites can be seen in Overview, but not in galaxy. The distance between a satellite and its “escorting” fleet is equal to sum of satellite's and fleet's diameters, but not less than 50. Fleet's diameter depends on amount and sizes of its units (the distance between units of same type inside the group is equal to 3 unit diameters).
Satellites disappear from the map at a distance of more than 50 000 km from the local coordinates centre, but remain on the list of satellites on the planet's panel.
At a distance of more than 100 000 km from the centre of local coordinates, satellites disappear from the list of satellites on the planet's panel of the galaxy.
At a distance of more than 1 000 000 km from the center of the local coordinates the space becomes unstable due to the complexity of binding and the distant location of the object with a strong gravitational field or the center of the intersection of the gravitational fields.
How to find an object in 3D Overview?
1. Spy the needed object.
2. You will find local coordinates (X:Y:Z) of all objects in the report. Hint: the planet, the asteroid is always on (0:0:0).
3. In the overview of the planet, the camera is at Y = 0. Therefore, if the desired object Y > 0, it should be searched in the upper half, otherwise in the lower half.
4. Advanced: Knowing the radius of the planet, a simple comparison with the Y value of the desired object can be roughly estimated how far the object is from the edge of the planet.
