Risk+Assessment.

//**Risk assessment**// Asteroids have been missing earth by just a million KM recently most astronomers think it is bound to happen sooner rather than later in 1989 on the 23rd of March an asteroid missed Earth by million KM and no one saw it coming that is the bad news. In 2016 the comet Swift-Tuttle will pass by under a million KM. What is worrying only a small change in its predicted path will make it hit us. The US department of defence told us they discovered many explosions in the upper atmosphere which were meteorites they self destructed when they entered our atmosphere which is worrying because there is a high chance that this will happen again. A meteorite 10 metres across would have a greater impact than the.Atomic Bomb itself. we have conducted some to show what would if something did hit Earth. these were the results: results.xls we made the trend line longer to show what wold happen from a more realistic height.
