The "inertia" of the moving planet combines with the force of gravity
between the planet and the Sun, causing the planet to move in an orbit around the Sun.
"Inertia" is basically the tendency for a moving body to move in a straight line unless acted upon by a force (such as gravity).
For a planet to stay in it's orbit the forces must be in balance.
Interia and gravity combine to make a planet stay in an orbit.
its falling and it has interia
The gravitational pull of the planet Saturn keep it's rings in orbit.
I believe meteoroids don't stay in orbit . . . they kind of just wander around in space, however planets have an orbit so they have a set path to stay on.
The gravity of a planet does not hold it in place, nor does any planet stay still. The planets are in constant motion as they orbit the sun.
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".
Unless acted on by an external force, yes.
The moons stay in orbit around Jupiter due to the gravitational pull of the planet. As of June 2014, Jupiter has 63 known moons.
Comets don't orbit a planet, they orbit the sun.
No, Venus does not orbit a planet. It orbits a star, which is our Sun. It can not orbit a planet , if it did it would be a moon
Satellites stay up in space due to how fast they are traveling. If an object is in motion around a planet at the correct speed it will orbit it without crashing towards the planet.
