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.

The suns gravitational pull causes the earth and other planets to the sun?
All the planets in the solar system are kept in orbit by the gravitational pull of the sun. The effect of the other planets and other bodies in the solar system is to change the shape of the orbits slightly but the sun is what keeps them in orbit around the sun.
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.
Why do planets remain in orbit?
They stay in orbit because of the suns gravitational pull.
Why does the Moon have a greater influence on Earth's tides than the Sun does?
Fancy boy
What causes planets to orbit?
Planets are kept in their orbit by the suns gravity, yet their momentum keeps them from falling into the sun. (Thank goodness!) Planets orbit in the direction their star rotates, so in our solar system, all planets orbit in the direction of the star.
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
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.
Can there be gravity between mars and earth?
All celestial bodies exhibit some kind of gravitational pull on all other bodies. Hence, yes, it is very much possible to figure out the pull between the Earth and Mars. So yes, there can be, and is, gravity between our planets. Needless to say, the effect of Mars gravity on earth is overwhelmed by the effect of the suns gravity on earth. But it still exists.
How do the planets of our solar system orbit the sun?
The Suns gravitational pull.
