Once
ignited
,
the
Sun's
powerful
solar
winds
____________________
to
blow
.
These
winds
,
which
are
____________________
up
of
atomic
particles
being
____________________
outward
from
the
Sun
,
slowly
pushed
the
remaining
gas
and
dust
out
of
the
Solar
System
.
With
no
more
gas
or
dust
,
the
planets
,
minor
planets
,
moons
,
comets
,
and
asteroids
stopped
growing
.
You
may
have
noticed
that
the
four
inner
planets
are
much
smaller
than
the
four
outer
planets
.
Why
is
that
?
Because
the
inner
planets
are
much
closer
to
the
Sun
,
they
are
located
where
the
solar
winds
are
stronger
.
As
a
result
,
the
dust
and
gas
from
the
inner
Solar
System
was
____________________
away
much
more
quickly
than
it
was
from
the
outer
Solar
System
.
This
____________________
the
planets
of
the
inner
Solar
System
less
time
to
grow
.
Another
important
difference
is
that
the
outer
planets
are
largely
____________________
of
gas
and
water
,
while
the
inner
planets
are
____________________
up
almost
entirely
of
rock
and
dust
.
This
is
also
a
result
of
the
solar
winds
.
As
the
outer
planets
____________________
larger
,
their
gravity
____________________
time
to
accumulate
massive
amounts
of
gas
,
water
,
as
well
as
dust
.
