Not necessarily! System with one sun (star) at its centre is called solar system. A solar system may have anything. Our solar system has, of course eight planets, asteriods, comets. But any other solar system in the cosmos may have different things,
they were formed the same time as the planets (after our sun)
It is called "The Oort Cloud"
If you mean all our planets and comets, it's called the Sun. It is called "The Solar System".
No. Most comets are about the same age as the solar system as they formed with it.
A group of heavenly bodies is called a solar system. Heavenly bodies are the stars, planets, comets, asteroids, and moons of a solar system.
All the comets that have been seen in history were in the solar system and most still are.
The solar system.
that is called the Oort cloud and that's where comets come from.
There are no visible comets at this time.
I scientifically believe that comets are closer to the outer part of the solar system.
The sphere far outside the Solar System is called the "Oort Cloud", after the astronomer who predicted its existence.
