What Is Solar System?

Solar means sun, while a system means a combination of different part working together as a whole. In short solar system is a system of sun and object that surround it. Our solar system formed 4.5 billion years ago from the cloud of gas called nebular. Sun is at the centre of the solar system. Our solar system comprises sun, planets, satellite, comet, asteroid and meteorites.

Is an arrangement of heavenly (celestial) bodies that orbit the sun.
Is a system of the sun and objects that surround it
Is gravitational bound system of the sun and objects that around it.
Is an arrangement of the objects that are revolving the sun and they are been affected by its gravity.

The time by which these objects are revolving the sun depends on their distance from the sun. For example, mercy uses a few days to complete its revolution while Pluto uses a lot of time than any planet. This is because Pluto is very far from the sun.

All these objects are revolving the sun in their path called orbit. This orbit is not completely round like a ball. Orbit has a shape called Ecliptic shape. Most of these objects are rotating on their axis at a certain angle. All these objects are held by the sun's gravity.
