Gravitational attraction to the sun
Gravity and velocity (inertia) keeps planets in orbit around suns.
Gravity - from the sun.
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
it keeps it in orbit
All planets orbit around a sun.
The Sun's strong gravity keeps all the planets in orbit around it.
The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
the gravititonal pull does; it is what keeps all the planet in the suns orbit xx
The Sun's strong gravity keeps all the planets in orbit around it.
It keeps them in orbit.
the suns gravity keeps the planets in orbit

Gravity and velocity (inertia) keeps planets in orbit around suns.
the gravitational pull from the sun keeps the planets and other small things in the orbit of the sun.(;
As the planets orbit the sun, its gravity keeps them from colliding
