no.
There is a single sun in our own solar system, but not in the universe. There are trillions upon trillions of suns (or stars) in the universe.
No. Even in our own solar system it is 2nd smallest planet. The biggest planet in the solar system is Jupiter.
No. Our own galaxy contains several hundred billion stars (each of which might be a solar system), the observable Universe contains hundreds of billions of galaxies, and it seems that the entire Universe is much, much bigger than the observable Universe.
Our moon, Luna, is indeed similar to many other moons even in our own solar system, much less the universe as a whole (which has not really be examined in sufficient detail to enable us to catalog moons in other stellar systems).
No one knows for sure. No one has a telescope powerful enough to see every star in the universe
No. Neptune is in the same solar system that we are.
Jupiter is not in the center of the universe, but rather at the center of its own orbit within our solar system. Its position is determined by the gravitational forces acting on it by the sun, which is at the center of our solar system.
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.
No, the solar system is just the same give to the system of planets which orbit the Sun. There are millions of similar systems in this galaxy and there are millions of galaxies in the universe.
Yes, for our solar system is just one of the many solar systems of the universe. In the universe, there are countless galaxies such as our Milky Way, which contain countless solar systems such as ours, that is located on an arm of the Milky Way. Solar systems are just systems of planets, asteroids, comets, etc kept in revolutions around a star from the force of gravity. There are many more stars out there besides just our star, which could just be random stars or could be big enough to create a solar system. Thus, there are many objects out there besides our own solar system. Hope this helps!
Galaxy. Solar system contain planets and stars. While thousands of stars makes up a GalaxyA Galaxy.Our Milky Way Galaxy is ~100,000 light years across.Our Solar system is a mere ~0.005 light years across.
Our own galaxy has between 100 and 400 billion stars; there are hundreds of billions of similar galaxies in the OBSERVABLE Universe, and it is believed that the entire Universe is much, much bigger than the observable Universe (how much bigger, is not known). It seems that at least a large percentage of those stars have planets, which means they can be called "solar systems".
