A review of David A. Weintraub’s Is Pluto a Planet?

This is the first review of the literature on Pluto. Here I look at David Weintraub’s Is Pluto a Planet? Weintraub supports Pluto’s planetary status and is, probably, still upset that the IAU’s definition of a planet excludes Pluto.

Govert Shilling: Pluto is Icy Chunk of Space Debris

Govert Shilling’s The Hunt for Planet X is the second review in my survey of the literature on Pluto. Unlike Weintraub, Shilling does not think Pluto deserves the status of planet. It seems that for Shilling, the IAU’s decision in 2006 was long overdue.

Published before the recent brouhaha over Pluto’s planetary status, Hoyt’s book on Pluto concentrates on whether or not Lowell deserves credit for predicting Pluto’s discovery.

Is there Life or Water on Mars?

Recent articles about the presence or absence of water on Mars seem remarkably familiar. More than a century ago Percival Lowell made life on Mars a popular and a scientific question. Bookies no longer take bets on finding life on Mars while astronomers continue to argue about the evidence and what it implies.
