QUESTION:
Are there hurricane seasons on Neptune or Pluto?

ANSWER from Heidi Hammel on June 10, 1996:
The answer to the first question is: we haven't been studying these
distant planets long enough to know the answer.  Ask again in a decade
or so!   In both cases, the seasons on those planets are so long that
we haven't even seen a full year yet!  

The "year" on Neptune - which is the time it takes Neptune to make a
complete trip around the Sun - is 165 Earth years, but Neptune was only
discovered 150 years ago!  The seasons (each about 1/4 of the Neptune year
long) are therefore more than 40 Earth years in length. We haven't been
able to study Neptune that long with high resolution cameras like those
carried by Hubble or Voyager to understand how its seasons work.   

Things are even more difficult for Pluto, since its "year" is 249 Earth
years (!) and it was only discovered 66 years ago (the rough equivalent
of only 3 months ago in Pluto time).
