An Extreme Cousin for Pluto? Possible Dwarf Planet at Solar System Edge

The current definition of &quot;Dwarf Planet&quot; bothers me.<p>Was Jupiter a dwarf planet before it cleared its orbit?<p>Was Earth a dwarf planet shortly after its collision with Theia, when there was presumably debris left in orbit?

&gt; 2017 OF201<p>That sounds like a Borg name. ;)
