Apophis Asteroid Could Hit Earth In 2036? Is Doomsday imminent in 2036?

Everyday more and more astronomers are waking up to the idea that perhaps the Earth is in danger.

According to NASA, On Friday the 13th, April 2029 asteroid 99942 Apophis with larger than two football fieldswill be perilously close to earth and will be within range to wipe out geosynchronous satellites.

Now some Russian astronomers are recalculating Asteroid Apophis’s trajectory and now say that there is a strong possibility that it will slam into Earth on April 13th, 2036. Professor Leonid Sokolov of the Petersburg State University was quoted as saying, “Apophis will approach Earth at a distance of 37,000 to 38,000 kilometers on April 13, 2029. Its likely collision with Earth may occur on April 13, 2036,” during an interview with Russian state television and broadcast by the Russian RIA Novosti News.

The name Apophis was given to this asteroid, named after the Egyptian god Apep, aka “The Uncreator”. Donald Yeomans, head of NASA's Near-Earth Object Program Office."Technically, they're correct, there is a chance in 2036 [that Apophis will hit Earth]," But the good news is that chance hitting it on Earth is just 1-in-250,000, Yeomans added.

If this is true, time flies so fast and next thing you know is 2036 is around the corner, what do the governments do on Earth against these potential hazardous asteroids?
