'Fern' (distant) is closely related to the noun 'die Ferne' (the distance). If something is 'fern' (distant), it is 'in der Ferne' (in the distance).
Er schaute sehnsüchtig in die Ferne.
He gazed longingly into the distance.
'Fern' (distant) is the first part of many useful words that all have to do with distance, e.g. 'das Fernsehen' (television), 'die Fernbedienung' (remote control), or 'das Fernweh' (desire to travel).
Kannst du mir bitte die Fernbedienung geben?
Can you please give me the remote control?
The noun that appears with 'fern' (distant) reveals the exact meaning: 'fernes Land' (distant country, spatial), 'ferne Zukunft' (distant future, temporal), or 'ferner Verwandter' (distant relative, personal).

far / wide
'weit' and 'fern' can both describe a great distance. 'weit' is very common in everyday language and fits with paths, routes, and distances: a place is 'weit weg' (far away) or the way is 'weit' (long/far). 'fern' also means 'far away', but often sounds a bit more elevated or poetic. You hear it, for example, in 'in der Ferne' (in the distance) or 'ferne Länder' (distant countries). Learners may confuse the words because both express spatial distance. As a practical rule: in normal everyday sentences, 'weit' is usually more natural, while 'fern' fits better in a somewhat special or less direct style.

Am Horizont sieht man ferne Berge im Abendlicht.
On the horizon, you can see distant mountains in the evening light.
Der Bahnhof ist zu weit, wir nehmen lieber den Bus.
