Composition of Neptune

Question:  What is Neptune made of?
bob w whitbeck


Answer:  Neptune, like Jupiter, Saturn, and Uranus, is a so-called
"gas giant" planet.  They are made of mostly hydrogen, methane,
ammonia, and some helium...
When I was younger (much younger!) I found it amusing to invent
palindromes that contained the names of the planets:
"Neptune? NO, one nut pen."
