The Planets - Orbit.
The attraction of gravity between the Sun and the planets
causes the planets to move around the Sun
in an almost circular path.
This circular path is called the planet's orbit.
The direction of the pull of gravity is always towards the centre of the mass.
If gravity is pulling
the Earth into the centre of the Sun,
why does the Earth move in a circle?
Why doesn't the Earth crash into the centre
of the Sun?
