What would happen if the inertia of the earth was increased without he sun's gravity increasing?

Inertia is measured by an object's mass.
The Earth would still go around in the same orbit, because the orbit does not depend on the mass of a planet.
"Inertia" is sometimes used to mean "momentum". That's mass times velocity.
If the Earth's velocity increased then it would move further from the Sun.
<<>> The point is that "inertia" is a nonscienific word that is used to describe different things by different people and it's best to use "mass" or "momentum" depending on what is meant.

What makes gravity a vital factor within our universe?
Without gravity everything would fly off into space, including us. Gravity keeps the planets in orbit around the Sun, and keeps the Moon in orbit around the Earth. Without gravity, we would be weightless.
What force creates and guides the sun's surface phenomena?
The force you are thinking of of is gravity. Well not so much the gravity but the gravitons in the gravity witch give it the force it has. Without gravitons it is actually a very weak force.
Why do astronauts need artificial gravity when in space?

Light from a star travels from earth in a straight line at a constant speed of 300000 kilometers per second What is the acceleration of the light?
The speed of light is a constant, so the acceleration is zero. However, light IS affected by gravity, and gravity causes an acceleration. How does this balance? The light moves at the same speed - the speed of light, abbreviated "c" - but loses or gains energy as the light moves toward or away from the gravity source. In gaining energy (without speeding up!) the frequency of the light is increased and the wavelength of the light (or any electromagnetic energy) is decreased, In losing energy, the wavelength is increased and the wavelength decreased. This could be a trick question, of course. Light from a star wouldn't be travelling from earth, unless we are talking about reflected light, which would not be particularly intense, but it is not out of the question.
Why is a Idle speed control solenoid important?
The Idle speed control serves a few functions such as increasing the idle when the vehicle is cold to keep it from stalling. It also responds to increased engine load such as when you turn on the air conditioning or turn the steering wheel at idle. Without the idle speed solenoid the vehicle would stall nearly every time you came to a stop.
If you have increased the momentum of a moving object without increasing its inertia then you have?
increased the velocity of the object
Why is mass a useful property?
Mass has two significant consequences, which are gravity and inertia. Without gravity we would have no planets or stars, since interstellar gas clouds would never condense. And without inertia, it would be really hard to play tennis.
How can the kinetic energy of a truck be increased without increasing speed?

Gravitational force works in straight and direct direction but rotating of the planets around the Sun are in circular paths How could the gravitation force impact in this way?
The revolution (not rotation) of the planets around the sun is not an example of straight gravity. It is a combination of two forces: gravity and inertia. Gravity, working without inertia, would pull the planets into the sun, in a straight line. Inertia, working without gravity, would send the planets sailing through the galaxy, in a straight line. The total effect of these two opposing forces is an orbital path. Gravity and inertia, in this situation, are also referred to as centripetal and centrifugal forces.
How do planets stay in their orbits yet not get sucked in to the Sun?
Gravity and inertia both contribute to their orbits. Inertia tends to move a planet away from the Sun, while the Sun's gravity tries to pull the planet closer. Without one of them, a planet would either float away from the Sun (inertia only) or burn up from the Sun (gravity only).
How does inertia affect your solar system?
Inertia keeps the planets revolving around the sun instead of just running into the sun. Since gravity pulls masses together, without inertia, all the planets would be pulled into the sun.
Is weight of a body is a measure of inertia?
No, a body's inertia is related to its mass and movement. Weight is related to a body's mass in a gravity field without movement.
What attractive force keeps the moon in orbit around earth?
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.
How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
How could absorption in the intestine of an earthworm be increased without increasing the intestines length?
Folding of the intestinal wall into intestinal villi, like in our gut.
How the kinetic energy of a truck could be increased without increasing the truck's speed explain?
Increase mass For a truck increase the load on the truck
What causes spiciness to increase?
Spiciness is increased by adding more spices to the food. Spiciness cannot be decreased except by increasing the amount of the food without increasing the amount of spices.
