That is a good question which was answered by Isaac newton who had to invent the science of calculus to explain it. In fact the earth moves in a circular orbit (approximately) and one of the implications is that it is constantly accelerating towards the centre of the circle, in this case the sun, which is where the force comes from.
It's a centrifugal effect that you can see by whirling something round on a string. The force in the string is more if the object goes quicker. Replace the string by the force of gravity and that is why the planets move in the orbits they do.
In fact it had already been discovered by Kepler that the planets move in ellipses, but a circle is not a bad approximation in the case of the planets, and it explains why it took so long to discover that.
If the earth started with zero speed, it would move towards the sun in a straight line, moving quicker and quicker until it plunged in to the sun after about ten weeks.

Why do the Moon's gravity have a greater effect on earths ocean tides than the suns gravity?
Even though the suns gravitational pull is stronger than the moons and does infact effect the tides slightly, the moon is close enough to pull the tides more than the sun. Its all distance related.
The suns gravitational pull causes the earth and other planets to the sun?
Yes, the sun's gravitational pull is what keeps Earth and the other planets in our solar system in orbit around it. This gravitational force is what maintains the planets' paths and prevents them from moving off into space.
Why do you notice the pull of earths gravity but not the pull of the suns gravity?
The center of the sun is very roughly 23,000 times as far from you as the centerof the Earth is.That means that the gravitational force between you and each pellet of mass inthe sun is roughly1/(23,000)2 = 1/(540 million) = 0.00000000185 as much asthe gravitational force between you and each pellet of mass in the Earth.The sun has roughly 333,000 times as much mass as the Earth has. So the totalgravitational force between you and the sun is333,000/(540 million) = 0.000617 as much asthe total gravitational force between you and the Earth.
Why does the Moon have a greater influence on Earth's tides than the Sun does?
Fancy boy
What percent of earths gravity does sun have?
The Sun's gravity is about 28 times stronger than Earth's gravity at the surface of the Earth. However, because the Sun is much farther away than Earth's own radius, its gravitational influence on Earth is significantly weaker compared to Earth's own gravitational pull.
Which type of tide is creates when the suns gravitational pull on earth is the least?
Neap tide
If the average distance between Earth and the Sun were doubled what changes could occur in the Suns gravitational pull?
Its pull on the earth would be 25% as strong.
Why is the earths orbital velocity fastest at perihelion?
the suns gravitational pull is strongest because the earth is at its closest point to the sun.
Why Do The Earth And Sun Mve Around each Other?
The su does not move the earth moves around the sun by the suns gravitational pull
Why do the Moon's gravity have a greater effect on earths ocean tides than the suns gravity?
Even though the suns gravitational pull is stronger than the moons and does infact effect the tides slightly, the moon is close enough to pull the tides more than the sun. Its all distance related.
How does the sun effect all the planets in the solar system?
They are all orbiting the Sun, therefor all in the Suns gravitational pull.
What happens to the pull of gravity when the sun and moon at right angles?
The Gravitational pull on the oceans is Partially canceled out by the suns Gravitational pull.
What happened to the pull of gravity when the moon and sun are at right angles?
The Gravitational pull on the oceans is Partially canceled out by the suns Gravitational pull.
What keeps the planets in your solar system?
The suns gravitational pull.
The suns gravitational pull causes the earth and other planets to the sun?
Yes, the sun's gravitational pull is what keeps Earth and the other planets in our solar system in orbit around it. This gravitational force is what maintains the planets' paths and prevents them from moving off into space.
How do the planets of our solar system orbit the sun?
The Suns gravitational pull.
How does the suns gravitational pull affect the speed at which planets orbit?
When the pull is stronger, they move quicker.
