Default Quantity Over Quality (Was: Unwritten policy and the intent of the average amateur ...)

As far out as the Moon, I'll bet - say, how far is that, anyway?


About 250,000 miles. Varies because the orbit is not a perfect circle.


have conflicting figures here from
some 'engineer' in this group, who
will remain useless.....


Who is that, Leo?


That was you.


No, it wasn't. You are mistaken, Leo.


I'm sorry, Jim - you are incorrect ..... once again!


I have posted the approximate distance from the earth to the moon here
a few times. 250,000 miles, each time.


A bit too approximate, OM - it varies considerably as the distance
changes during the orbit cycle:

Mean distance: 238,712 miles
At apogee: 252,586 miles
At perigee: 221,331 miles

That's a 11% error rate at perigee, and approaching a 5% error rate
at mean distance. Not too far off at apogee, though - perhaps we can
get someone to hold it still for you?

You're definitely well within amateur-level expectations, but not
likely to cut it at the MSEE level, though.....

But you were much closer than you were with your Mars calculations!
One of them went over a 100% error rate.

(just in case you forgot again, you can find that one with Google if
you search the groups for the following subject line: " European
Mars probe to use 80meters to look for Martian water?" - August 7,
2004, to be precise).

You're welcome!


Ptoooey - did you forget?


Ptoooey?


Ptoooey.

No signoff again? Bad form!

(why be 'approximate' when exact is so easy?)
