similar
to
the
other
outer
planets?

1.
Scientists
predict
the
existence
of
Neptune
before
it
was
discovered.
They
noticed
that
Uranus
was
not
always
located
exactly
where
it
should
be.
They
assumed
that
gravitational
pull
of
another
planet
beyond
Uranus
was
affecting
Uranus
orbit.
Neptune
was
discovered
in
1
846
in
the
position
that
had
been
predicted
2.
Neptune
is
similar
to
the
other
outer
planets
because
Neptune
has
rings
of
ice
and
dust.
3.
Neptune's
weather
is
very
cold.
The
winds
on
Neptune
are
stronger
than
those
on
any
of
planets
in
our
solar
system,
reaching
speeds
of
1,100
kilometers
per
hours.
Neptune
is
one
of
the
coldest
places
in
the
solar
system.
4.
Scientists
think
that
Triton
did
not
form
near
Neptune
because
the
moon
orbits
in
the
opposite
direction
to
the
orbit
of
Neptune
and
it
has
a
pure
circle
orbit.
they
think
that
Triton
did
not
form
near
Neptune
but
instead
was
captured
by
Neptunes
gravity
as
it
passed
by.
