Hi Bill and Others,

After installing the August 24 version of Guide 8, I was perusing the More
Info box for Mars and I saw the Hill sphere radius listed as 319.8. No units
are listed, but I am assuming that is in thousands of kilometers although I'm
not too sure about that because the value given for Jupiter is only 740.
Please explain what units are assumed. As a nit pick for some future update,
you might include units with all data shown in the More Info boxes.

BTW, my calculation for the Hill radius for Earth is about 1.5 million Km. I
was wondering if you have a table of physical data for Earth anywhere in
Guide. Such a table might be useful whenever someone wants to make
comparisons of measurements of other bodies to those of Earth.

Thanks for the help.
