Each planet remains in orbit because of the pair of equal gravitational forces
that attract it and the sun toward each other.
If you mean "why don't they orbit other objects in our Solar System", the Sun has most of the mass in our Solar System.
Yes, each of the 8 major planets has its own orbit, with no asteroids or other objects in its path.
All planets and other objects in the solar system orbit the Sun because of its gravity.
This is called the solar system
It is called the solar system. Except that the sun has only 8 planets.
That is called the Solar System.
This is the definition of our solar system.
Orbit
Yes, the solar system consists of a large central star (called the sun for our solar system), with planets that ore in orbit around it. There are other bodies in orbit around the sun also, such as minor planets, asteroids, comets, and other small objects.
