Kenneth, Pluto has a radius of 1188 km, but is still rejected by many as a Planet (when I was a kid it was a Planet). This new one seems much smaller than Pluto?? But has a highly elliptical orbit?
A new solar system discovery points to a ninth planet. (No, not Pluto).https://www.nytimes.com/2018/10/02/science/goblin-planet-nine.html …

This one isn't a planet, but there seems to be something that's a super Earth/mini-Neptune out there (not yet found) that's nudging the orbits of these smaller things.

Excuse my ignorance, but how is it possible to find planets on other solar system but yet we are missing one in the own backyard?

It’s easier to find your keys if you drop them under a street lamp. It’s easier to find distant planets (and moons) if they happen to pass in front of the star because you can measure how much the star dims. Much harder if they’re in the back of a dark closet.

Could they make their minds up? Or just take a vote? Or / and stop teaching about the solar system in school till then?

The problem is that the famous “missing planet” has a highly eccentric orbit far away from the nearest gas station, so it’s difficult to stop and ask for directions... It was “discovered” through detecting anomalies in the orbits of other bodies, leading to a theoretical planet
