Factual error: After crashing on the asteroid, A.J. walks outside surveying the wreckage while debris is strewn out burning on the ground. This is wrong, as oxygen is needed to make something burn, and there is no oxygen in the asteroid.

Factual error: When a scene is showing people all over the world just before the shuttles take off, it is daylight everywhere. It would actually be dark or near dark in parts of the world.

Other: A.J. gets dirt on his face although he is covered by an astronaut's suit.

Continuity: At the end of the movie, after the asteroid explodes, we see Grace looking through the glass and there are reflections of NASA controllers cheering. The same shot was used earlier in the film to depict Grace looking upset at some bad news. The camera zoomed into the picture a bit, but you can still see one controller cheering.

Continuity: When Harry is going to A.J's room, he bangs on the door with a golf club. You can see the white fan fall to the ground. Then when Harry walks in the fan is back on the ledge.

Revealing: There's grass on the edge of the cliff when the Armadillo finally lands - look just under the Armadillo while the astronaut's pulling himself up the road. Considering this is an airless, waterless asteroid, it doesn't really fit...

Continuity: The first meteor is a direct hit on a street vendor in NY where the dog is chewing on one of his Godzilla figurines. To start with he's chewing a small Godzilla, then it cuts to the vendor tugging on it, then it cuts back and its suddenly a much larger one.

Continuity: When they are in the shuttle trying to disarm the bomb, it is the pilot that is telling the munitions specialist, the guy that is supposed to know everything about the bomb, which wires to cut.

Continuity: Even thought the second shuttle takes off later then the first, they are neck and neck when they clear the atmosphere.

Continuity: When in the Russian space station, AJ is in a little pit fixing something. When we see him, he has a little snow hat. The next time he has nothing on. Then back again with the little hat.

Continuity: After Sharpe and Stamper have the argument on the asteroid, Truman says they need the radio back up. When he says this, you see the countdown clock for the asteroid which is at five hours and 12 minutes. A bit later in the film, after the nuke was shut down by a technician at NASA, one of the military officers takes the terminal. In the background, you can see the clock again but the time on it is at six hours and 49 minutes.
