Astrid Peth performer Kylie Minogue
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". Subsequently, much of the episode's success in terms of viewing figures was attributed to Minogue's appearance in the role.
