The planets in trouble; Pluto, Saturn, Mercury, now Jupiter

First, Pluto was demoted.

Next, GM killed Saturn.

Then, Ford killed Mercury.

Now, Jupiter is under attack.

When will the madness end?

(thanks Rick Klau for reminding me of Saturn)

    Pluto Is still a planet. Only four percent of the IAU voted on this, and most are not planetary scientists. Their decision was immediately opposed in a formal petition by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto. Stern and like-minded scientists favor a broader planet definition that includes any non-self-luminous spheroidal body in orbit around a star. The spherical part is important because objects become spherical when they attain a state known as hydrostatic equilibrium, meaning they are large enough for their own gravity to pull them into a round shape. This is a characteristic of planets and not of shapeless asteroids and Kuiper Belt Objects. Pluto meets this criterion and is therefore a planet.
