Rogue planets Memes

The International Astronomical Union is shaking right now! This chaotic alignment chart completely demolishes the official planetary definition with gleeful scientific anarchy. For those not deep in astronomical drama: in 2006, astronomers defined planets as objects that 1) orbit the sun, 2) are round from their own gravity, and 3) have "cleared their neighborhood" of other objects. Poor Pluto failed test #3 and got demoted to "dwarf planet." This chart throws those rules into a black hole by declaring everything from Earth to comets to literal spacecraft as planets. The inclusion of PSR J1719-1438 b (a planet made of diamond orbiting a pulsar) and rogue planets (planetary-mass objects floating through space) shows just how wonderfully unhinged this classification system is. Justice for Pluto... and apparently for Voyager too!
