A meteorite with a 1km diameter will undoubtedly cause global damage. It is believed that a meterite a bit larger was responsible for the extinction of dinosaurs. Rocks this big only appears to hit Earth once every 100 million years.

Will an asteroid hit sydney in the year 2029?

Chances are, no. There was some concern in 2004 that the asteroid Apophis might hit earth in 2029, but it is now known that the object will narrowly miss earth, though there is still some uncertainty of a few thousand miles as to how close it will come. There is still a very slight chance that it could hit earth in 2036.Even if we did predict that an asteroid would hit earth, we could not predict the path so precisely as to whether it would hit a particular city.

How do scientists work out if an object from space will hit earth soon?

Orbital ephemera. They consider its position relative to the sun, earth/moon, and other planets. Over a period of days they can determine its orbit, and whether that orbit likely intersects ours.
