h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

according to http://arxiv.org/abs/1003.5911 dated in 2010
my early article on Quaoar A86154546 is somewhat in error.
New diameter figure for the Dwarf Planet is 890km and for its moon weymot approximately 75 km.

sorry- I have a key sticking.
that article should have been A861446

You say in the article:

The International Astronomical Union would call this a KBO (Kuiper Belt Object) but with a diameter of 1,280km (800 miles) it is large enough to be considered more than just one of the billions of small chunks floating around in the Kuiper Belt. One source stated that there would fewer than ten objects beyond Neptune which were this large.

Would both these facts still be true now that the size of the object is smaller?

Oh, and can you write up a sentence or two about the satellite and tell us exactly where you want it to be placed.

Here is more information.

Apparently we need to also put in a sentence about the density.
It is 54.2 plus or minus 1.3 grams per cubic cm.
therefore when I say a snowball the size of Australia, I really should say a rock the size of Australia.
About the moon
Weywot rotates around Quaoar every 12.5438 days at a distance of 14,500 km.
It was this knowledge that allowed a recalculation of the size and composition of Quaoar itself.

also the comparison to Australia was using the old size calcualtion.\
The first sentence should probably read " a rock the size of Texas".

that density figure shown above is way high.
I am having problems with the four and five keys on this keyboard.
I meant to say 4.2 not 54.2

About the moon
The info about the moon should go with a new sub-header above the also rans.
Weywot rotates around Quaoar every 12.438 days at a distance of 14,500 km.
It was this knowledge that allowed a recalculation of the size and composition of Quaoar itself.

More information on the moon.
It was discovered in 2007 and named by a tribe of Native Americans in California. It has a diameter of 74 km and is five magnitudes fainter than Quaoar.

So the new paragraph should be
Weywot
Quaoar's moon Weywot was discovered in February 2007 by ME Brown and TA Suer using the Hubble Space Telescope. The moon is five magnitudes dimmer than Quaoar and is roughly 74 km in diameter.
It rotates around Quaoar every 12.438 days at a distance of 14,500 km.
It was this knowledge that allowed a recalculation of the size and composition of Quaoar itself.

See post 54 about the first line of the article.
then in the section also rans
<> should be changed to it is slightly smaller than Quaoar.
with those modifications I believe the article will be up to date.

of course there is no post 54 here
I meant post five.
The article begins
<> I was suggesting that be replaced with Like a rock the size of Texas, this world circles the Sun at a distance so great that any visitors would find it hard to tell to which star it was attached.

I'll do these, Shagbark.
