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.

Who is that, Leo?

That was you.

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

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

Nope. The earth-to-moon distance is approximately 250,000 miles.

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

In your opinion.

- it varies considerably as the distance
changes during the orbit cycle:

As I noted when I wrote:

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

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.

Nope.

Not an "error rate".

The figure 250,000 miles is accurate to within 11.5%.
(approximately) at perigee, using your figures.

Twice in each orbit, the earth-to-moon distance is exactly 250,000
miles, btw.

*Not too far off at apogee, though - perhaps we can
get someone to hold it still for you? *


If 250,000 miles isn't accurate enough for you, then you must fault
your buddy Len too. Because he stated the distance as a quarter
million miles....

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).

Yup, I made an error on the Earth-to-Mars distance. So what? The error
was corrected.

Did I call anyone names for pointing out m,y mistake? Did I make fun
of their education?

You're welcome!

Ptoooey - did you forget?

Ptoooey?

Ptoooey.

No signoff again? *Bad form!

73, Leo

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

No reply? *Worse form.... *

Why should I reply to someone who is anonymous?

(how can someone argue vehemently an error of only 0.04% in one
thread, and be as much as 11 percent out in this
one *- and over 100
percent in another?? *That just ain't logical!!)

Who is arguing over an error of 0.04%, Leo?
Certainly not me.

Len claimed:

"that Technician class is now bigger
than ALL other US license classes combined"

But he was wrong. 100% mistaken.

Even if we allow the inclusion of Technician Pluses in the total, they
do not exceed the number of all other US license classes combined. The
difference is more than 0.5%, not 0.04%.

But the percentage difference doesn't matter. Len did not specify
"approximately" or cite any numbers in his claim

"that Technician class is now bigger
than ALL other US license classes combined"

All he did was make the claim, which is either true or false. Only two
possible states - true or false - not a question of approximations or
percentage of accuracy.

I showed Len's claim to be false - using the numbers Len provided!
Those numbers are exact, not approximations.

In short:

The earth-to-moon distance is approximately 250,000 miles. Both Len
and I agree on that.

Twice per orbit, the earth-to-moon distance is exactly 250,000 miles.

but

The Technician class is *not* now bigger
than all other US license classes combined.
And if present trends continue, it never will be.
