I independently determined the orbit of 2005 YU55 using nothing but observations from amateur astronomers. The result shows a slightly closer approach than when professional data is included, but it still passes us almost just as far away, at a safe distance of about ~242,528 km. It misses the moon according to this orbit by ~165,230 km.


Even the amateur data shows that earth is safe... for now ;). Yes, eventually some damaging rock will hit earth again, but not this one, at least not in our lifetime. Nonetheless, we should remain vigilant.

Unfortunately, 2005 YU55 won't be close enough to be visible to the naked eye, but it will put on a good show in telescopes. Provided the weather allows for it, I will be broadcasting a live view of the asteroid's close approach here on GLP.
