Thus I implied that Planet X had an ABSOLUTE magnitude of 2.0 but an
apparent magnitude of 11 at present when seen from Earth. I, NANCY,

approximately 9 Sun-Pluto distances from Earth. What the ZETAS stated
[Planet X is approximately magnitude 2.0 in brightness ...

And John has correctly taken umbrage, above.
