Apophus, named after the Egyptian god of of death and darkness, more than 1,000 feet across is scheduled to pass so close to the earth in 2029 it could first cause atmospheric disturbances before it returns on Friday, April 13th 2036 for a real close encounter and possible terrestrial impact with our planet.
Michiu Kaku Discusses the highly probable earthly impact of a large asteroid in 2036. Watch the video here:
Researchers at NASA/JPL, Caltech, and Arecibo Observatory have released the results of radar observations of the potentially hazardous asteroid 99942 Apophis, along with an in-depth analysis of its motion. The research will affect how and when scientists measure, predict, or consider modifying the asteroid's motion. The paper has been accepted for publication in the science journal “Icarus” and was presented at the AAS/DPS conference in Orlando, Florida in October of 2007. The Apophis study was led by Jon Giorgini, a senior analyst in JPL's Solar System Dynamics group and member of the radar team that observed Apophis. Failure could spell disaster upwards of 1,500 miles
