Why won't KSP recognise my space station as such?

[ThatBurger]

I am trying to build my first Space Station. I have now docked multiple pieces together in space, but the game doesn't recognise the vessel to be a Space Station in the tracking centre (it falls under 'ships'). The station can accommodate 7 Kerbals and has batteries, solar panels, Science devices and lights. Can anyone help me to understand why the vessel is not recognised as a station in the tracking centre? Are there any particular requirements (in terms of structures, functions, etc.) for it to be considered a space station?

no, there aren't any special requirements. the tracking station assignment is done according to some parameters that I don't know, but they are quite random. my last ship was dubbed a plane just because it had a Mk3 crew cabin, even though it had no wings.

anyway, it makes zero difference. if it's to fulfill a contract, then as long as it has the crew capacity and the parts specified, you are fine. if you just want to see "space station" in the tracking station, you just have to manually set your station as such.

go to your station, select any crew pod or probe core, right click on it, "configure vehicle name". there you can also decide if your vessel is a station, plane or whatever
