Each planet would move away from its orbital path in a direction tangential to the orbit. That means roughly "sideways" from a line between the Sun and the planet.
Literally a solar system has the Sun at the centre because solar means 'of the Sun'. But to have a system of planets you need something massive at the centre to provide the gravitational force to control the orbits. Without that, the planets will just go off in straight lines.
Not all the planets orbit the sun - other stars have planets too. But all the planets in our solar system, which is the system of our sun, revolve around the sun; otherwise they would be in other solar systems. All the planets we can see with our naked eye orbit the sun, since the planets orbiting the sun are the only ones close enough to earth to see without a telescope.
perturbations
Each of the planets, moons and asteroids are actually moving fairly quickly. The Earth, for example, has an orbital speed of a little upwards of 66,000 miles per hour. Without gravity to keep things orbiting, everything would continue in a straight line straight out into space.

Since the Sun has the most mass of all the objects in the solar system, it has the strongest gravitational pull. If there were another object in the solar system with more mass than the Sun, the planets (and the Sun itself) would orbit it. If there were no Sun's gravity (or other gravitational forces) the planets would travel in straight lines instead of orbits.

Three of them were grabbed by the gravitational pull of the local star. There are planets that are not in our solar system.
