I came across this link from
William Shatner's new Scifi creative network
The link discusses celestial objects in or relative to
Our solar system that are classed
As something other than planets
For reasons we're not entirely sure of.
The sun's evil twin reminds me of the Neighbour Star Nemesis
In Isaac Asimov's book Nemesis, which I just read.
And just why is Ceres not being discussed?
