Re: Planet X: What SIZE to Expect?

Is Jim correct?  On August 7, 2002, Planet X will be 1/139 the size of 
Jupiter?  What does this translate to in the scopes of amateurs, size-wise? 
From Jim:

...................................
Unless I missed something here this is not rocket science. 
All approximations, figures rounded:

(Px=4x dia. Earth, Jupiter=11 dia. Earth, 
    therefore Jupiter=2.75 dia. Px)
Jupiter mean dist. from earth is .484B mi. 

8/7/02 Px 24.5B mi. 
24.5B/.484B=50.6 times Jupiter's 2.75=139. 
    Px is 1/139 view size of Jupiter 
    (not allowing for trailing, swirling moons.) 

4/2/03 Px 5B 5B mi.
5B/.484B=10.3 times Jupiter's 2.75 dia Px=1/28th size of Jupiter. 

4/30/03 Px 1.2B mi.
1.2/.484B=2.4 times Jupiter's 2.75=1/7th size of Jupiter.
