Bad astronomy

i thought the sun blinding the astronaut was true i was right because the sun close enough can cause blindness. i also thought that it was possiblew to track a meteors path. this is also true tho it takes a long time for the data to be calculated

i thought the speed of the comet was also fake. i was correct, a comet would be moving way faster than what was shown in the movie. another thing i thought was fake was the size of the tidal wave. i was wrong though a tidal wave could easily be that size from a comet
