Will Apophis Hit Earth in 2036? NASA Rejects Russian Report
By Michelle Bryner | Space.com
In 2004, NASA scientists announced that there was a chance that Apophis, an asteroid larger than two football fields, could smash into Earth in 2029. A few additional observations and some number-crunching later, astronomers noted that the chance of the planet-killer hitting Earth in 2029 was nearly zilch.
The asteroid Apophis was discovered on June 19, 2004. It will fly within 18,300 miles of Earth on April 13, 2029,
but poses little risk of impact.UH/IA
Now, reports out of Russia say that scientists there estimate Apophis will collide with Earth on April 13, 2036. These reports conflict on the probability of such a doomsday event, but the question remains: How scared should we be?
Technically, theyre correct, there is a chance in 2036 [that Apophis will hit Earth]," said Donald Yeomans, head of NASAs Near-Earth Object Program Office. However, that chance is just 1-in-250,000, Yeomans said.
The Russian scientists are basing their predictions of a collision on the chance that the 900-foot-long (270 meters) Apophis will travel through whats called a gravitational keyhole as it passes by Earth in 2029. The gravitational keyhole they mention is a precise region in space, only slightly larger than the asteroid itself, in which the effect of Earths gravity is such that it could tweak Apophis path.
The situation is that in 2029, April 13, [Apophis] flies very close to the Earth, within five Earth radii, so that will be quite an event, but weve already ruled out the possibility of it hitting at that time, Yeomans told Lifes Little Mysteries. On the other hand, if it goes through what we call a keyhole during that close Earth approach
then it will indeed be perturbed just right so that it will come back and smack Earth on April 13, 2036, Yeomans said.
The chances of the asteroid going through the keyhole, which is tiny compared to the asteroid, are minuscule, Yeomans added.
The more likely scenario is this: Apophis will make a fairly close approach to Earth in late 2012 and early 2013, and will be extensively observed with ground-based optical telescopes and radar systems. If it seems to be heading on a destructive path, NASA will devise the scheme and machinery necessary to change the asteroids orbit, decreasing the probability of a collision in 2036 to zero, Yeomans said.
There are several ways to change an asteroids orbit, the simplest of which is to run a spacecraft into the hurtling rock. This technology was used on July 4, 2005, when Deep Impact smashed into the comet Tempel 1.
