Inertia is defined by Newton's first law,
"Objects in motion stay in motion, objects at rest stay at rest"
If a planet had no inertia it could come to a stop or accelerate to high speeds without any force applied to it. It also would not find an orbit.
Inertia is a fundamental property of the law of conservation of energy.
Without it, the planet, and the universe would be quite, quite different.

If gravity or inertia stop working what would happen to the earth?
If gravity and Inertia stopped working the planet would fly or float away from he sun and get EXTREMELY cold. And everything will die.
What two factors combine to keep the planets in their orbits?
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.
What would happen to a human if they traveld to planet mercury?
they would problobly die or get frozed
What two factors keep a planet in orbit around the sun?
Gravity and inertia
What effects the revolution time of each planet?
The size of the planet and the inertia it begins with. Inertia is the resistance to changing velocity (either speed or direction). All objects in the universe are already moving, so the planet, while moving, was caught in gravity of another object (like the Sun) and trapped in revolution. The amount of inertia, determined by mass, normally, influences how fast an object revolves.
What would happen if there was no inertia?
There would be no life on the planet. By:karean colson-marshall (karin)
What would happen to an object in orbit around a planet if the planet's force of gravity were stronger than the object's inertia?
The object would crash into the planet.
What would happen to an object in orbit around a planet if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.

What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
What would happen if a planet had no interia?
If a planet had no intertia, it would stop orbiting its star, it would stop spinning on its axis, and it would simply sit there, unmoving relative to its solor system, except when it was hit by a moving object that did have inertia. Even the smallest particle with inertia would cause our planet to be pushed ahead of it until our planet rolled off of the particle to one side or the other. Since your question did not indicate an absence of gravity, too, then objects on the planet including its atmosphere would remain there. If there was life on the planet, all the life forms dependent on day/night cyles would wither and die.
What force is responsible for the orbit of the planet in the solar system?
That would be gravity and inertia.
What force counteracts a planet's inertia and keeps the planet in its orbit?
Gravity counteracts this inertia, usually the gravity of a body much larger than itself.
What tries to make planet move in a straight line?
Its inertia.
Does a planet have the greatest inertia?
It depends on what type of planet it is.... which one is it?
If the moon did not have inertia as it travled around the earthwhat would happen?
If the moon suddenly decided to stop pusing forward (inertia), the balance between inertia and the earths gravity would cease and the moon would come crashing into us. :)
Why does a planet a planet keep orbiting the sun?
Inertia is trying to pull the planet away from the sun and gravity is pulling the planet toward the sun so the both inertia and gravity steer the planet around the sun
