So this month's decision by a meeting of the I.A.U. in Prague has re-drawn the boundary of our Solar system. Pluto is classified as a 'dwarf planet'. OK, I realise that definitions are important in a field of study where things like celestial mechanics are supposed to be an exact science, but this curious astro demotion still sounds like Plan B for Planet 9 to me.

I never liked Pluto anyway. I've always been a fan of Mercury myself.
