As you have no doubt heard, Asteroid 2005 YU55 will pass inside the orbit of the moon at about 85% of the distance to the moon.
Will it go close to the Moon? Not really, as it will cross earth’s orbit at a distance almost as far above the orbital plane as it is distant from us along the plane.
Still, that is very close in Astronomical terms and no (known) object of this size will pass this close again for another 17 years - 2001 WN5, which is a whopper at about 1 Klm wide, will come through at bout 0.7 LD (Lunar Distance) in June 2028. Then in 2029, Apophis makes its really close pass on April 13th, which I really hope isn’t a Friday, but the path is well known with very low uncertainty and it too will pass safely by. So this is a very exciting event and will receive lots of coverage, with great opportunities to grab great photos and create videos.
