gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
The inertia of earth combines with gravity to keep it from colliding with the sun
The two key factors that keep Earth in orbit around the Sun and the Moon in orbit around Earth are gravity and inertia. Gravity is the force that attracts the Earth and the Moon towards the Sun and Earth, respectively, while inertia is the tendency of an object to maintain its state of motion. The balance between these two forces results in stable orbits; gravity pulls the objects inward, while inertia causes them to move forward in space. This interplay creates the elliptical paths that define their orbits.
Gravity and inertia
Gravity is what keeps them in attraction. The force of Gravity is determined by the mass and distance between two or more objects. The other force that keeps the moon in orbit is the moon's inertia. Without inertia the moon would simply fall into Earth; because of Gravity, the same would happen with the planets and the sun.
The two forces that pull on planet Earth to create its orbital path around the Sun are gravity and inertia. Gravity is the force that attracts the Earth towards the Sun, while inertia is the tendency of Earth to continue moving in a straight line unless acted upon by an external force, in this case, the gravitational pull of the Sun.

Newton concluded that the combination of the gravitational force between the Earth and the Sun, and the Earth's inertia moving it in a straight line, keep the Earth in orbit around the Sun.
Gravity and Inertia keeps the earth in orbit
The force of gravity and the inertia of the Earth (as it orbits the Sun). Also, gravity combined with the inertia of the Moon (as it orbits the Earth).

The sun's gravity is pulling the planets toward it and the planets inertia keeps them moving forward

Gravity and Inertia
There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
Friction has 100% nothing to do this the Earths orbit, its gravity and inertia.
Gravity and inertia are the two forces that keep the moon and other satellites in orbit around Earth. Gravity pulls the moon towards Earth, while the moon's inertia keeps it moving forward in a curved path, resulting in a stable orbit.
