The Impossible Planet (1) - S2-E11
Factual error: Ida, the science officer, says that the planet is in geostationary orbit around the black hole. However, the word "geostationary" applies very specifically to objects orbiting the planet Earth. Since a black hole is a type of star, this planet's orbit could be described as astrostationary, or even just stationary, but definitely not as geostationary. A science expert on an interstellar mission wouldn't make this mistake, and she wasn't dumbing things down, either, since "geostationary orbit" is already a pretty obscure topic for people unfamiliar with space technology.

The Impossible Planet (1) - S2-E11
Continuity mistake: After Ida retracts the roof to show the black hole, there is a shot where the Doctor and Rose are looking at it, with nothing above them, as he explains about it. However, other shots of the base's control room show that there are things in the room, such as wires connecting the central computer table to the walls, that should have been visible. (00:08:00)
The Impossible Planet (1) - S2-E11
Continuity mistake: When Rose is talking to Danny about the Ood, in one shot she's holding her cup with two hands, only for her to be holding it with only one hand in the next shot. (00:11:25)
The Impossible Planet (1) - S2-E11
Continuity mistake: When Rose takes out her phone and finds there's no signal, she slides it open twice, in the wide shot and close-up. (00:23:15)
The Impossible Planet (1) - S2-E11
Continuity mistake: In shots of the base's Ood habitation area from above, the Ood are shown in four rows from left to right, with the Ood in the third row standing with their backs against the room's middle partition and the other rows sitting on benches. However, in a shot from inside the lower area when the Doctor and Rose first go to Ood habitation, the third row is shown sitting as well. Not until later in the episode, when Danny is ordering the Ood to remain in the room, is the third row shown standing again. (00:25:15)
The Impossible Planet (1) - S2-E11
Continuity mistake: When the Doctor and Ida descend into the core of Krop Tor, the screen charting their progress shows 39% Oxygen. After cutting away to an overhead shot of the two, the camera cuts back to the same descent display, only now the oxygen percentage (which has been descending constantly all this time) is at 42%. (00:35:25)
The Impossible Planet (1) - S2-E11
Continuity mistake: When the underground cavern is first shown, the descent pod is at the bottom of a pile of rubble up against the wall at the bottom of the drilled shaft. However, in the shot of the cavern shown when Ida says "My god, that's beautiful," the pod and pile of rubble is further away from the wall. (00:37:00)
The Impossible Planet (1) - S2-E11
Factual error: The graphics depicting the black hole show matter falling directly towards the centre of it. This would only happen if all the matter happened to be heading in that direction already. In reality, matter approaching the black hole at any other angle would swirl around the event horizon, like water going down a plughole.
Continuity mistake: When the Doctor first appears in the episode, baiting the Hoix with a piece of raw meat, the meat turns around in his hand between the close-up and the wide shot. (00:02:30)
Continuity mistake: When Ursula is filming Elton outside his old house, the digital camera produces a distorted picture and has four white lines in the corners. But, after Elton's flashback, Ursula is still filming but the picture is straight and the lines are gone. (00:04:40)
Continuity mistake: Jackie gets Elton to take his shirt off by deliberately making a huge red wine stain on the front. When Elton comes back to the estate with the pizza, his shirt is unstained. (00:27:17)
Continuity mistake: After the scribble creature has been analyzed and found to be made of graphite, the Doctor takes out a pencil and erases some of it to confirm this. The next time the graphite ball is seen, the erased area is gone. (00:14:35)
Continuity mistake: When the Doctor takes a swipe out of a jar of jam in Trish's kitchen and sticks his finger in his mouth, he only has his index finger in his mouth. The scene cuts to Rose giving him a "WTF" look, and when it cuts back to the Doctor he suddenly has two fingers in his mouth. (00:21:15)
Continuity mistake: When Rose grabs the drawing of the Doctor and the TARDIS from Chloe, the upper right corner is bent over rather sharply. In the close-up of the picture as Rose tells the Doctor she'll find a way to get him out of there, the paper is now only slightly wrinkled. (00:30:15)
Continuity mistake: When the Isolus leaves Chloe, in the shot facing Chloe where it says goodbye, Chloe's hand is raised to the wall, where the two were drawing a picture of the Earth. In the wide shot where the Isolus leaves Chloe's mouth, her arm is lowered. In the next close-up of Chloe, when she says "Mum?", her arm is raised again. (00:36:05)
Factual error: The Police motorcycle in front of the Olympic runner is an S registration, meaning it was registered in 1998. The episode is set in 2012, and there is no way the Police would have such an old vehicle on active duty.
Factual error: The Olympic torch relay is presented as if there is only one runner carrying the torch through the entire city of London to the Olympic stadium to light the cauldron. Furthermore, when the torchbearer collapses, the TV announcer reacts as if it is now impossible to get the torch to the stadium, just before the Doctor steps in and picks it up. Any broadcast of any Olympic opening ceremonies would show that that's not how the torch relay has ever worked.
Chosen answer: No, no information is avalible for the identity of the entity.
