You couldn’t have watched ‘The Sky at Night’ the other week, Sticks. If you had you would have seen how they put these scare stories in context.

It’s difficult to accurately position these asteroids in space. The only way is to carry out measurements over a long period of time. That’s why meteors that make headline news one week turn out to be harmless the next.

As for small meteorites, these hit the Earth all the time but don’t pose (much) threat to us because they are slowed down from their cosmic speeds by the planet’s atmosphere. There hasn’t been an incident recorded in the last hundred years of a meteorite killing a person. Apparently though, two cows have bitten the dust in this manner.
