The episode had an overnight rating of 4.83 million, according to figures quoted by the BBC's entertainment correspondent Lizo Mzimba, which marks a slight dip when compared to the first of the 60th anniversary specials, The Star Beast.
The Star Beast became the biggest drama launch of 2023, as well as achieving the biggest overnight ratings for an episode of the sci-fi series since Resolution in 2019, with an overnight audience of 5.08 million.
The viewing figures for Wild Blue Yonder are yet to take into account the amount of people who watched the show via catch-up, which will be available after seven days.
Strictly was the night's big winner with 7.82 million, while I'm a Celebrity… Get Me Out of Here! managed 5.05 million.
