ages ago, because of a big explosion and then the debris was pulled together. it was known as the BIG BANG
solar systems
no Yes there are other solar systems .
We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
They are either other solar systems, nebulas (Dead solar systems) Blackholes, other galaxies or stars that have no orbits
nebula, dust, solar systems and other solar masses
The sun is the only star in our solar system.
The solar system has existed in its present form for about 4.5 billion years.
Matter is all the matters
We strongly suspect that every other solar system will be different, probably RADICALLY different, from our own. Every star is a little different; the mass that coalesced to form the solar system is different, and the unimaginably random factors that caused each solar system to form as it did - those are also different.
Our solar system has 1, Other solar systems are unexplored at the moment....
No. There is one star in our solar system, and no other solar systems within it.
Galaxies are vast collections of stars, gas, dust, and dark matter, typically containing billions to trillions of stars. Stars form from clouds of gas and dust within galaxies, and they often have their own planetary systems, known as solar systems. Each solar system consists of a star and the celestial bodies that orbit it, including planets, moons, and asteroids. Thus, stars are the building blocks of solar systems, while multiple solar systems together make up a galaxy.
