NEO Asteroid 99942 Apophis caused a stir eight years ago when it was calculated that it would make close passes by the Earth in 2029 and 2036, and possibly collide. It has since been determined that a collision in 2029 is not possible, and one in 2036 is given only a 1/250,000 likelihood.
Meanwhile the approximately 270-meter wide asteroid is predicted to pass less than 0.1 AU from the Earth on 2013 JAN 09. Greatest brilliance for this apparition at magnitude +16.1 is expected on JAN 20.
I’ve created three preview graphics with data related to the January apparition of Apophis. They can be seen on my asteroids webpage at: www.CurtRenz.com/asteroids
Photos and descriptions of Apophis would be welcome additions to this thread.
