Hi,
Like old age, capture, at least orbital capture,

they being, respectively, death and impact!

Hi, Rob, Doug, List
Why am I always digging myself out of holes that I apparently made with my
own mouth? Well, better than extracting one's own feet from that same mouth, I
guess.
There are many definitions of phase angle. Leaving out the ones that
apply to periodic and wave

Jeje, Hola Jerry,
Yes, if the counterpart balls in the pool hall had a sort of magnetic
attraction that could transfer momentum without touching (i.e, gravity)

MOON Trojan objects exist.
They are the Kordylewski clouds, small faint patches
of dust, at the L4 and L5 points of the Earth-Moon
system (not Earth-sun system). The Kordylewski clouds
have been photographed, and have even been seen by the
naked eye under total dark skies. They may be variable
Hi,
Thank you, Francis, for supplying the name that slipped through the
cracks in my brain at three o'clock in the morning. I knew it started
with K and was Slavic, but that's as far as my brain went, and my
Googling finger was numb with overuse.
They were a subject of derision when
Hi Sterling, Doug, and any other lurking List members still following the

Yes, phase would be about 2/3rds if it was spherical, but small bodies

Hi Darren, Sterling and List,
Sterling pondered about Earth Trojans:
Makes me wonder if somebody has ever tracked the orbital points
60 degrees ahead and behind the Earth... Wouldn't it be great
to have Trojans of our own?
Certainly astronomers have tried, but small objects at L4 and L5
Hola Rob,
Wouldn't that be = 2/3's (gibbous) phase = about 66% illumination, and a
maximum average sky angle of a comfortable,high 60 degrees max observed angle
(+/- the oscillation) ... checking they're equilateral triangles, though
intuition might be wrong?
