Breaking News- The Moon MAY have an Asteroid Orbiting iit!
UPDATES WILL BE POSTED ASAP! Check back.

Looking at some of the links and some further googling, I  get the impression that XG02E65 and S509356 are two different objects, the former passing the Moon Earth system relatively close by and the second in an elliptic orbit around the Earth actually (not around Moon).

Latest update for another expert!
It's an ordinary Near Earth Asteroid,
Period is 1.96 years, which means it's orbit around the sun take 1.96
earth years, or 715.4 days. It is not in orbit around the moon.

XG02E65 as possible asteroid in moon orbit!
- Preliminary Data Suggests Possible!  IF this is proven this will be the first of such ever observed!
{MPML} XG02E65 = possible radar target, needs astrometry!

Based on magnitude the object is 16-20 meters!
Spectral data indicates that this is NOT man-made object and is a rock, and a possible S-type asteroid.

Photometry-
Dogs Heaven Observatory, Brasillia, Brasil

Just a note that I've received more astrometry for this object.
In particular, I just got PanSTARRS data via Peter Veres that
extended the arc back a month, to early February. Put that together
with new data from (Y28) OASI and (474) Mount John, and we get...

http://www.projectpluto.com/pluto/mpecs/s509356.htm

...which gives an area/mass ratio of 0.00759 +/- 0.00040. On
top of that, there are some strange trends in the data that look as
if there are some more complicated forces going on here. (Which tends
to happen when we've tracked an artsat for a couple of months. The
simple model I use, that "sunlight is pushing this object away from
the sun", becomes a little _too_ simple.)

But in any case, that AMR tells me we'll have to drop any hopes
of a "mini-moon".

I've not been very positively inclined to the idea that there might
be a "mini-moon" out there in the first place. (My major objection is
that I don't see how you'd get into this sort of orbit, nor stay in
it stably for really long time spans. Then again, Phobos got into
an orbit like this, so I may be overlooking something.)

But if this fairly bright artsat has been orbiting the earth
undetected for decades, it suggests to me that _if_ there are mini-moons
out there, we could have overlooked them, too. Even boulders a few
meters across. I do find that to be an interesting thought.

Other Object-
SONEAR asteroid survey discovered an object in geocentered orbit yesterday,
with PANNSTARS later providing precovery imagery from a week earlier.

The object is called S509356 and is in a weird distant orbit with apogee at half
a lunar distance, perigee near geosynchronous altitude. Inclination 48 degrees,
period 3.58 days.
