Solar City

 was a large, cosmopolitan city on the planet of Galactica Minor. An overcrowded and polluted spaceport, it attracted a wide variety of sentient species. The Seventh Doctor visited the planet and made enemies of some of its — possibly temporary — residents. He also encountered a reporter named Miff who worked for the local Universal Herald, who unsuccessfully tried to get an interview with the Time Lord. (COMIC: Once in a Lifetime)
