The Earth Got Buzz by the Asteroid 2017 AG13 -- 50% Closer Than The Moon

On  2017 Jan  7  at  7:39:30.24(UTC) the Catalina Sky Survey discovered an asteroid on route to buzz the Earth. They submit their observations to the Minor Planet Center(MPC) and the "object"(with their observations) was posted the NEO Confirmation Page.  Observers from around from the world took follow-up observations and on 2017 Jan  8 at 15:14(UTC) the Minor Planet Electronic Circular announcing the discovery. On 2017 Jan  9 at  ~12:49 (UTC) buzz the Earth at ~  0.5 Lunar Distances (LD) -- to put things in perspective"If" the Earth Was the Size of a Basketball this would be ~ 12.80 feet(3.90 meters)  away.

The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15.


The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15. The idea was to take advantage of the total lunar eclipse get useful images of a "desirable" NEO. The moon position was within 25 degrees from the imaging target ((387733) 2003 GS).... if this was a "normal" full moon It would have mostly likely been too "close" to get "good" Images.
