Mercury:
The
Small
but
Mighty
Planet Mercury
is
the
smallest
planet
in
our
solar
system,
but
it
packs
a
big
punch.
With
its
close
proximity
to
the
sun
and
lack
of
atmosphere,
Mercury
endures
some
of
the
most
extreme
conditions
in
our
solar
system. One
of
the
most
interesting
features
of
Mercury
is
its
rotation.
It
rotates
so
slowly
that
it
takes
59
Earth
days
for
it
to
complete
one
rotation
on
its
axis,
but
it
orbits
the
sun
in
just
88
Earth
days.
This
means
that
Mercury
experiences
some
of
the
greatest
temperature
swings
in
our
solar
system.
During
the
day,
its
surface
can
reach
up
to
800
degrees
Fahrenheit
(427
degrees
Celsius),
and
at
night
it
can
drop
to
as
low
as
-290
degrees
Fahrenheit
(-180
degrees
Celsius). Mercury
is
also
the
planet
with
the
greatest
temperature
extremes.
Its
poles
are
permanently
shadowed
and
remain
in
darkness,
and
scientists
believe
that
they
contain
areas
where
water
ice
may
exist. Despite
its
small
size,
Mercury
has
a
surprisingly
large
impact
on
our
solar
system.
It
is
believed
that
its
gravitational
forces
have
helped
shape
the
orbits
of
other
planets
and
asteroids.
Additionally,
NASA's
Messenger
spacecraft

years

sending
back
valuable
information
about
the
planet's
unique
geology,
history,
and
evolution. In
conclusion,
Mercury
may
be
small,
but
it
is
a
force
to
be
reckoned
with.
Its
extreme
conditions
and
slow
rotation
make
it
a
fascinating
and
unique
planet,
and
its
impact
on
our
solar
system
cannot
be
understated.
