View Full Version : The "Pluto disappearance graph"

According to legend, someone plotted the various estimates of Pluto's mass on a graph and concluded that it would eventually disappear completely. Does anyone know when it was composed, and by whom?

BA mentions that joke here (http://blogs.discovermagazine.com/badastronomy/2007/10/12/sharpest-image-of-pluto-ever-taken/), FWIW.

Thanks! Wow! That article's fantastic! It's also confounding. Who was J. Babinel and how was he predicting Planet X two years after Neptune was discovered? I need to know!!!!

I don't know when the "disappearing Pluto" graph first appeared, but I first heard about it in late '67 or early '68 from an astronomy professor in college.
