Conversely, if Apophis is a small, less-massive prograde rotator, it arrives a bit later on April 13, 2029, and the uncertainty region for 2036 is advanced along the orbit. Only the remote tails of the probability distribution could encounter Earth, producing a negligible impact probability for 2036.
2036 April A METI message Cosmic Call 2 sent from the 70-metre Eupatoria Planetary Radar on July 6, 2003, arrives at its destination, HIP 4872. 2036 March 27 The 99942 Apophis approach to Earth on March 27, 2036, will be no closer than 0.30889 AU (46.209 million km; 28.713 million mi; 120.21 LD).

A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
It gained some public interest when it became clear, in January 2005, that the asteroid 99942 Apophis would miss the Earth in 2029 but may go through one or another keyhole leading to impacts in 2036 or 2037. Further research has since been done, however, which revealed the probability of Apophis passing through the keyhole was extremely low. [1]
Keeping an eye on Apophis during and after its close approach to Earth could enable scientists to see whether there are any shifts in its orbit that could affect the likelihood of it hitting Earth ...
Within a few years, they were able to dismiss the even smaller chance of a hit in 2036. Images of the asteroid Apophis, captured in 2012, allowed scientists to determine that it will not strike ...
For example, it was estimated there was a high chance of 99942 Apophis swinging by Earth in 2029 with a 10 −4 probability of returning on an impact trajectory in 2035 or 2036. It was then determined that a deflection from this potential return trajectory, several years before the swing-by, could be achieved with a velocity change on the order ...
Apophis, a space rock roughly 1,200 feet (366 meters) across, will come within 20,000 miles (32,187 kilometers) of Earth in about 5 ½ years, which is closer than satellites that orbit our planet ...
