Not any time soon. In about 4 or 5 billion years, the Sun will expand in to a red giant, at which time it may expand enough to swallow up the Earth.
Our Earth is not in a falling orbit.
It is falling through space even though moving around the sun. The inertia of the "fall" and the pull of the gravity of the sun, make the earth go around the sun in an ecliptic orbit.
Gravity is caused by mass, so objects with more mass, such as planets and stars, exert a lot of gravity. The earth and everything on it are constantly falling towards the sun because of the sun's immense gravity. ... Because of this sideways momentum, the earth is continually falling towards the sun and missing it.
It prevents the earth from spinning off in a straight line away from the sun instead of falling back into the sun.
in my opinion nucular radation from the sun or things on earth.
The earth is falling. It takes the earth an entire year to fall once around the sun.
Zero, assuming current conditions. However, when the sun runs out of hydrogen in roughly 5 billion years, it will expand and then collapse. It is not clear whether earth will remain a burned out cinder orbiting the dead sun, or will be literally consumed (falling through the earth's surface) during the sun's expansion.
if the earth did not orbit the sun, and was stationary in space, it would simply be pulled towards the biggest force of gravity available (the sun). it is only the centrifugal force of the earth rotating around the sun that stops the earth from falling into the sun
Then it would fall into the Sun. It is the Earth's movement (of about 30 km/second) that keeps it from falling INTO the Sun.

Earth is falling.Earth is falling freely around earth but due to inertia it dosent drops on sun it revolves around the sun just like a satellite.When a body falls in the absence of air(air friction)then it is said to be freely falling since there is no air in space therefore Earth is said to be freely falling.
None at all. The Earth is a big rock, falling around the Sun in its orbit. It expends no energy at all.
