Why do the Planets Revolve Around the Sun?
If
the planets
did not revolve, the Sun's gravitational pull would drag them
inwards. If
they moved very quickly, they would fly off into the space. The closer
a planet
is, the faster it must
move. All
the planets move in
the same
direction, because
probably they
were formed
from the
same spinning cloud
of material
that also made the
Sun. All the
planets except
Venus and
Uranus spin in
anti- clockwise
direction.
