Gravity counteracts this inertia, usually the gravity of a body much larger than itself.
inertia
The object would crash into the planet.

Gravity is the force that holds a planet in orbit around the sun. Inertia keeps the planets spinning.
inertia
Gravity and inertia. Inertia keeps the planets moving while the gravity of the sun keeps the planets drawn to orbit in ellipses.

Gravity is the force that holds a planet in orbit around the sun. Inertia keeps the planets spinning.
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
The force of gravity pulls the planet towards the Sun and this is balanced by the planet's "centrifugal force" away from the Sun. (Centrifugal force is called a "fictitious force" in physics. It's a mathematical way of representing the planet's tendency to move in a straight line path. Some people prefer to talk about the planet's "inertia" rather than centrifugal force.)
Gravity and inertia.
1) The gravitational attraction between the planets and the Sun. 2) The "inertia" of the planets. That's their tendency to move in a straight line unless a force (gravity in this case) acts on them.
None do. If the forces on a planet were balanced, then it would take off in a straight line at constant speed, not remain in orbit. The only force acting on a planet is the gravitational one, that attracts the planet toward the sun. Fortunately, that's the only force required to keep the planet in orbit.
