[meteorite-list] Fw: Comet 17P (Holmes) Visible Event !

[mexicodoug]

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
