How close to a station you need to be for it to stop showing up as undiscovered?

I sometimes get really close, even shoot it, but for some reason it still shows as undiscovered on the galaxy map which is really frustrating. Shouldn't the name be on the map automatically as soon as it shows on my radar? (N)

I think they show up for me at 3K roughly. Yep you would think if the name appeared on radar it should appear on map. However, you could also say that it requires visual confirmation that it isn't transponding a false radar ID.
