New evidence suggests there might be. It was unexplained perturbations in the orbits of the known planets that led us to Pluto, after all ( the actual ninth planet, no matter what the pointy heads say).
Reminds me of Isaac Azimov's book "Nightfall."
There are a number of Kuiper Belt Objects out there that while not "planets", are roughly the size of Pluto -- this would be much larger apparently.
ReplyDeleteBy the way, I still consider Pluto a planet.
We are Plutophiles.
