Anybody been keeping an eye on QO104? It now has 4 Torino Scale 1's on
its Risk Chart. One in 2009. http://neo.jpl.nasa.gov/risk/2003qo104.html Check the close approach in 2034! Anybody put up any images of it yet? |

I notice the 2009 date went away, But there is a 2031 date with a 1.51 Earth Radii miss. Anybody know why there are two close approaches on the same date 2034? And other dates, two solutions? http://neo.jpl.nasa.gov/risk/2003qo104.html#legend Two encounters are give on the same date, why is that? 2034-05-19.24 2034-05-19.46 Ron Baalke kindly answered my question: "The fractional part is the time, so they are different dates. We list all potential impacts, and it is possible to have a couple close to each other. We take 10,000 potential starting positions of an asteroid and propogate them forward in time. If any of them impact the Earth, the asteroid gets listed on our risk page along with all of the potential impacts. The one you pointed out is where two of them just happen to potentially impact the Earth very close to each other in time. " Ron Baalke |

The risk page is sure interesting to watch. http://neo.jpl.nasa.gov/risk/2003qo104.html The solutions at 2034 is still there, at less than 2 Earth Radii. Will probably change again. But 2 of the Torino 1's have dropped off the risk list. This guy such has a lot of passes inside the Moon's orbit. Kind of wish JPL would put up a non-body animation for this kind of guy since those close passages must change its orbit. |
