If we are 1AU from the sun, and this planet is 90AU from the sun, then it is between 89 and 91 AUs from earth depending on the progress of our orbits (assuming perfectly circular orbits). So they did change the frame of reference.
This far-flung orbit may be the result of an encounter with a giant planet, which ejected the candidate dwarf planet out of the solar system, say the researchers.
Poor guy. Hopefully he’s out there finding his own family.
At least it doesn’t have to deal with the toxicity Pluto does, being in the family one day and then coldly rejected from the family from the planet club the next. And we wonder why it’s exterior is frozen…
It turns out that for all of these different methods, you will find an extremely clear bimodal distribution that groups the 8 planets together as being highly capable of clearing their orbits whereas everything else falls into a statistically distinct non-clearing group. This is because there's sound dynamic reasons for why objects would fall into one group or the other with nothing lasting long in the "grey area" between them. Once an object becomes significantly better than its orbital neighbors at clearing the neighborhood it snowballs due to the feedback loop of scattering or absorbing its neighbors into itself.
That makes this a good criterion for classification. As the old saying goes, "cleave nature at the joints."
When we hit the floor you just watch them move aside
We will take them for a ride of rides
They all love your miniature ways
You know what they say about small boys
Ugh, didn’t read the “dwarf” part and got my hopes up for planet 9. When they eventually do find it they have to name it something with P so that the old mnemonics still work.
