The Sky at Night S31E09 · The Hunt for Planet Ten

Overview

Is there a tenth planet? New evidence seems to indicate that there is in fact an extra member of the solar system, moving far beyond the paths of the most distant planets now known, Pluto and Neptune. Patrick Moore discusses the whole problem, and speculates as to what Planet Ten may be like - if it really exists!
