Pluto in True Color
Explanation:
Pluto is mostly brown.
The
above picture captures the true colors of
Pluto
as well as the highest surface resolution
so far recovered.
No
spacecraft has yet visited this
most distant planet in
our Solar System.
The
above map was created by tracking brightness
changes from
Earth of
Pluto during times when it was being
partially eclipsed by its moon
Charon.
The map therefore shows the hemisphere of
Pluto that faces Charon.
Pluto's brown color is thought dominated by frozen
methane deposits metamorphosed by faint but
energetic sunlight.
The dark band below
Pluto's equator is seen to have rather complex coloring,
however, indicating that some unknown mechanisms
may have affected
Pluto's surface.
