Many folks would like to see us back on the Moon and developing its resources.

One more time - Earth Second Moon or "Other Moon"

Well something like this has happened before.

Remember the Apollo 12 booster stage that visited us?

Earth's "Other Moon"
April 17, 2007
by Roger W. Sinnott
Last September, when a tiny asteroid drifted into Earth�s vicinity, our
planet�s gravity captured it. The meter-size object, designated 6R10DB9,
is now making its third wide swing around Earth. It was quite faint,
magnitude 19.3, when discovered September 14th with the 0.68-meter
(27-inch) Schmidt telescope of the Catalina Sky Survey
<http://www.lpl.arizona.edu/css/> in Arizona, and it won�t get much
brighter than that.

�Certainly 6R10DB9, with a geocentric eccentricity less than 1, is
currently orbiting the Earth ,� says Gareth V. Williams of the Minor
Planet Center <http://cfa-www.harvard.edu/iau/mpc.html>, �although it
will leave the Earth-Moon system after next June�s perigee.� Williams�s
calculations show that prior to capture 6R10DB9 was in a low-inclination
orbit around the Sun with a period of about 11 months. That�s typical of
the paths followed by spent rocket boosters left over from space
missions of the 1960s and 70s.

When 6R10DB9 makes its final and closest pass in June, �threading the
needle� and dipping just inside the Moon�s orbit, astronomers will get
their best view of it for years to come. Spectroscopic studies with
large telescopes, for example, could help to reveal its true nature.

So that is at least two visitors that have been caught aah, �threading
the needle�.
Check out the link and see the expected loop de loops.

Then consider what one might be able to do if you could just do some
slight vector adjustments and circularize the orbit and do some mining
if this is an asteroid.

Also consider what will happen to the booster stages of the upcoming
lunar launches to the Moon.

Put them into orbit around the Sun, crash them into the Moon, or let
them fall back to Earth to burn up.

Hmmmm, as a kid I shot an arrow into the air. Came back on our shingle
roof. Dad wasn't happy.
Hope we do a better job of shooting arrows into the air in the future.

Thanks for looking up with me.

Orbit shows "second Moon" may be Apollo junk

A mystery object recently found orbiting the Earth is more likely to be
a used rocket booster from an Apollo spacecraft than a tiny second Moon.

NASA scientists have now analysed the object's orbit, which "indicates
that it could be a leftover Saturn V third stage from one of the Apollo
missions, most likely the Apollo 12 mission, launched on 14 November 1969".

The computer simulations were carried out by Donald Yeomans and Paul
Chodas at NASA's Jet Propulsion Laboratory. They show that the object's
orbit is consistent with a booster that circled the Earth in the 1960's
or 1970's, was then captured by the Sun and finally returned to Earth
orbit in April 2002.

The object was spotted on 3 September by an astronomer in Arizona and
was initially thought to be an asteroid passing the Earth. But further
observations revealed that a 50-day Earth orbit at an altitude rising
from 300,000 to 800,000 kilometres.
