While the object has the potential to wipe out millions of lives if it landed on a city, it is far smaller than the nine mile wide asteroid which is believed to have led to the extinction of the dinosaurs 65 million years ago.
According to sky scans carried out by NASA, there are around 19,000 "mid-sized" asteroids of between 330 and 3,300 feet wide within 120 million miles of Earth. All have the potential to destroy an area the size of a city were they to strike.

Won't be anything left to destroy if Apophis hits.
Possible impact effects NASA initially estimated the energy that Apophis would have released if it struck Earth as the equivalent of 1480 megatons of TNT. A later, more refined NASA estimate was 880 megatons, then revised to 510 megatons. The impacts which created the Barringer Crater or the Tunguska event are estimated to be in the 3–10 megaton range. The 1883 eruption of Krakatoa was the equivalent of roughly 200 megatons and the biggest hydrogen bomb ever exploded, the Tsar Bomba, was around 50 megatons. In comparison, the Chicxulub impact, believed by many to be a significant factor in the extinction of the dinosaurs, has been estimated to have released about as much energy as 100,000,000 megatons (100 Teratons). Path of risk where 99942 Apophis may impact Earth in 2036. The exact effects of any impact would vary based on the asteroid's composition, and the location and angle of impact. Any impact would be extremely detrimental to an area of thousands of square kilometers, but would be unlikely to have long-lasting global effects, such as the initiation of an impact winter. The B612 Foundation made estimates of Apophis' path if a 2036 Earth impact were to occur, as part of an effort to develop viable deflection strategies. The result is a narrow corridor a few kilometers wide, called the "path of risk", extending across southern Russia, across the north Pacific (relatively close to the coastlines of California and Mexico), then right between Nicaragua and Costa Rica, crossing northern Colombia and Venezuela, ending in the Atlantic, just before reaching Africa. Using the computer simulation tool NEOSim, it was estimated that the hypothetical impact of Apophis in countries such as Colombia and Venezuela, which are in the path of risk, could have more than 10 million casualties. An impact in the Atlantic or Pacific oceans would produce a devastating tsunami
