It is more like falling around the Sun. Earth is always falling into the Sun, but it's sideways orbital speed keeps moving Earth to the side of it's direction of fall. So the direction it would have to fall to hit the sun is different and Earth has to start over to get up speed falling in the new direction. This just keeps going on forever, falling toward the Sun but always missing it to one side. Of course, this takes enormous speed on the part of the Earth, about 66,000 miles per hour sideways all the time.

Laplace originally thought that the Sun was formed first by itself. And the planets were formed from the matter that shot out in rings from the Sun as it rotated. Other astronomers also thought as the Sun moved through the space, its magnetic field attracted dust and gases which eventually turned as planets. Jupiter, Saturn, Uranus and Neptune came into being as giant gaseous planets. The ones which are closer to Sun namely Mercury, Venus, earth and Mars because of the excessive temperature of the Sun the gases did not freeze and thus only the dust was left turned as lumps eventually becoming rocky planets. Hence even as Earth was to be formed the sun rings were rotating and hence the earth is revolving around the sun and naturally due to the gravitation pull of each other they stay in space.

earth is revolving around sun it is analogous to the electron is revolving around nucleous of an atom. There is many forces which tends the earth to revolve around the sun. The centripetal force and gravitational force of sun tightly bounded to earth and try to pull the earth to sun but also the centrifugal (psydoforce) force which push the earth from sun. These two forces tends the earth to revolve around sun.

The Sun is by far the most massive object in the Solar system and as a result exerts the most gravity on objects around it.This causes less massive objects to free fall toward its centre and thus orbit around it. Jules, lecturer. Australia.

The sun's enormous gravitational pull creates a "dent" in space time, makes it curve. The earth simply follows the outline of the curve.

because of the centripetal force provided by the gravitation.
