Fleets located on satellites are visible in the Overview, but not visible in the galaxy. The distance between a satellite and a fleet is equal to the sum of the diameters of the satellite and the fleet, but at least 50 km. The diameter of a fleet depends on the types, number, and sizes of its constituent units, which line up in globular groups. The distance between identical units in a group is equal to 3 diameters of a unit.
You are free to fly in the 3D Overview to a distance no further than 100 diameters of the object you are viewing.

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.
