QUESTION: 
I would like to know how Pluto compares in size to Earth or landforms of Earth.


ANSWER from Marc Buie on May 26, 1996:
The Earth is 12756 km in diameter, Pluto is 2300 km in diameter.  If you
superposed Pluto over the USA, Pluto would cover from the California coast
to the Mississipi River.  Check out this picture if you can,
