its falling and it has interia
Stay in orbit
For a planet to stay in it's orbit the forces must be in balance.
the rotation of the planet and its orbit
Interia and gravity combine to make a planet stay in an orbit.
Neptune
The gravitational pull of the planet Saturn keep it's rings in orbit.

I dont know...... sorry :) Hope I helped!?
You are thinking of Pluto. Pluto is now designated a minor planet.
All the planets orbit in a perfect circle, so they always stay the same distance from the sun, except Pluto, which is why it is now a "Dwarf Planet".
The gravitational force between the planet and the sun causes the planet to orbit the sun, keeping it in a continuous path. Additionally, the planet's inertia, or tendency to continue moving in a straight line, causes it to stay in motion around the sun.
The Sun's gravity causes a planet to orbit the Sun.
