Is everyone going to die in 2029?

It seems unlikely. Even I will only be 79 in 2029, and my family is noted for long life expectancy.

Oh, you were referring to the Friday, April 13, 2029 near pass by the asteroid Apophis? No, Apophis will certainly miss the Earth in 2029. However, it will come quite close to the Earth, and the Earth's gravity will deflect the orbit of Apophis very slightly, giving it a tiny but measurable probability of striking the Earth exactly seven years later, on Friday, April 13, 2036. (Note that BOTH passes will occur on Friday the 13th.)

Closer observations of Apophis' orbit during the CPA (Closest Point of Approach) in 2029 will allow us to more accurately predict the approach distance for the 2036 pass.
