It’s those people that for stupid sentimental reasons want Pluto to be called a planet again, like they learned in grade school. Even though they’ve never seen or ever will see the tiny ball of ice they hold so dear, they betray the very soul of science over it by saying their feelings are more important than empirical data.
It’s clear from the article that they are admitting they screwed the pooch back in 2006. They use Jupiter as an example, not Pluto.
This whole Planet definition thing sounds like a buncha Grant Proposals ganging up on the government for funding of nonsense.
