High Quality Content by WIKIPEDIA articles! Astrid Peth is a fictional character played by Kylie Minogue in the long-running British science fiction television series Doctor Who. She is a one-off companion of the Tenth Doctor who appears in the episode "Voyage of the Damned", which was first broadcast in the UK on 25 December 2007. Minogue`s casting in the role was a major coup for Doctor Who, her fame attracting much publicity for "Voyage of the Damned". The episode`s success in terms of viewing figures has been largely attributed to Minogue`s appearance in the role of Astrid Peth ("Voyage of the Damned` was the second most watched television programme of the entire year of 2007), though every `Doctor Who` Christmas special, both before and after has always attracted good ratings - the 2008 special `The Next Doctor` attracted almost identical ratings, and both the 2009 and 2010 specials rated well over 12 million viewers.
