The next asteroid to hit Earth could be Apophis. Deep Astronomy states that the asteroid, which was discovered in 2004, could hit on April 13, 2036.
Deep Astronomy explains that Apophis is expected to pass Earth within five Earth diameters on April 13, 2029. The exact path it takes on this date is expected to determine whether it passes by the Earth in 2036 or collides with it.
Newer observations and calculations presented by NASA's Impact Risk program predict a 1 in 256,000 chance or less of the asteroid's orbit being changed enough for Apophis to hit Earth, despite passing by at a distance of less than one Earth radius between 2060 and 2105.
