IN OTHER WORDS: ONE AU FROM THE OBJECT BETWEEN THE SUN AND THE OBJECT.
Sorry for the shouting mister Tholen, but: if it is ABSOLUTE (*ABSOLUTE*)
magnitude (AS I SAW NANCY SAY, "can't you see the difference between
absolute and aparent magnitude ???!!!")... if it is ABSOLUTE magnitude,
which it is so let me rephrase that: it is *absolute* magnitude, and since
that is aparently normalized for solar-system objects to 1 (1!!) AU, it
will dead-simple mean that Magnitude 2.0 is VERY possible, in the very
least it is nothing out of expectations.

What is this Tholen: what is this stuff with Magnitude while you know
all along it was suposed to be normalized on 1AU. 1AU is 1/354 of the
distance to P-X (using the average Pluto-Sun distance 9 times here).

I can hardly believe this. Is this it? Is that what absolute-Magnitude
means? (for solar-system objects?) MAN talk about your anti-climax.
What is this beckering about a thing that is no problem at all.

*GODDAMMIT*
Am I wrong here somewhere? it seems not, and I played it all hard, on
myself too (actually only being rational at all times).

Now I am puzzled again, only for different reasons so it seems.

*puzzle*
