I don't get it. I thought that Pluto's existence, like Neptune's,
had been deduced by pertubative effects on the other planets. But
if so, then why with our much greater precision of measurement,
and our immensely greater calculation resources, haven't all
bodies "of Pluto's size" and approximate distance been located
before this?
