We would freeze if we had no other source of heat or if we were to far away from the sun, or we would burn if our orbit forced us to get to close to a heat source like the sun.
It would get bigger
If the moon was on the left and the sun was on the right, it would suggest that the moon is in its waxing phase moving towards a full moon. This positioning is a natural occurrence based on the moon's orbit around the Earth and the Earth's orbit around the sun.
If only gravity were acting on Earth, it would continue revolving around the Sun in its elliptical orbit without any external forces to change its path. The force of gravity between the Earth and the Sun would keep Earth in its current orbit, so it would not be pulled closer to the Sun.
The magnitude of the gravitational force between the sun and Earth would decrease if Earth was placed in Pluto's orbit. This is because the force of gravity between two objects is inversely proportional to the square of the distance between them, so as Earth moved farther away from the sun (as in Pluto's orbit), the gravitational force would weaken.
The earth's constant orbit around the sun is caused by an equilibrium between two forces - the gravitational pull of the sun, and the earth's velocity acting at a right angle to it. If that gravitational pull was suddenly eliminated, the earth would continue onwards in a straight line.
It would get bigger
earth will fry up.
it would push it away
everyone would DIE! surely..
It is tilted (23.5 degrees).
If gravity were not a force between Earth and the sun, Earth would move in a straight line tangential to its orbit instead of orbiting around the sun. This would cause Earth to drift off into space, no longer held in orbit by the sun's gravitational pull.
They will hit Earth if, in their orbit around the Sun, they happen to cross Earth's orbit.
If the earth did not revolve around the sun, there would not be any seasons. The problem is that if the earth did not revolve around the sun, that is, if it came to a stop in its orbit, the sun's gravity (with just the tiniest help from the earth's) would pull the earth into the sun.
As the Earth does not rotate evenly, but rather at a tilt, the seasons would be skewed.

distance to the sun.
The magnitude of the force would decrease greatly.
