Hi Again Listees,

With regards to Comet 17P (Holmes) estimated at under 3.5 Km in diameter,
and being twice as far from the Earth as the planet Mars:

How could it be one sixteenth as bright as Mars and an easy object in the
night sky with an almost Full Moon? No doubt it has a lot of ice crystals
or something white and reflective. A rought thought says that in absolute
terms it is one fourth the brightness of Mars if they were at the same
distance from us! This is because we perceive only 1/4 of the light
intensity due to the doubling of distance,

It is it is hard to avoid the temptation of thinking this tiny body is of
relatively pristine material now confined to the Asteroid belt, but before,
from the Outer Solar System, and may, for once, given Jupiter his dues, have
been affected by a relatively close pass to the inner Solar System, with
Venus, Earth and Mars all aligned this month to exert their gravitational
attraction together. Not to mention all of the scientists and collectors
who would will material to Earth.

The comet is over 40% further away from Earth as it is from Mars at the
moment, so I hope the guys with their hands on the controls of the Mars
rovers take a break and look up for us at MidSolnight, and that the Deep
Impact Crew is already into emergency overdrive to make the comparison they
will be held accountable for, now that there is a second chance :-)...

Best Skies and great health,
Doug
