Some have been detected round other stars than the Sun. It is conjectured that million or even billions of stars must have their own solar systems, because without a solar system the average star would have so much angular momentum it would fly apart. Most of the solar system's angular momentum resides in the planets, thus keeping the Sun quiet and stable.

There are on the order of 100,000,000,000 (one hundred billion) galaxies in the universe, as far as current telescopes can detect. Some of these galaxies may hold up to 100,00…0,000,000 stars, but most galaxies probably contain at least 10,000,000,000 stars. Young galaxies under 2,000,000,000 years old may not have formed many solar systems yet, while very old galaxies more than 10,000,000,000 years old may have very few galaxies left. For the galaxies of middle age, as many as 1/4 of the stars may possess solar systems. My comment: While the answer above is true based upon current knowledge, it is essentially incorrect. The answer to your question is: ONE. Our Sun is named Sol - and the system of planets and other objects orbiting it are referred is referred to as "Solar", being of Sol. So other planetary systems exist, but they are not "Solar"... Comment: The above is incorrect, the answer above is for our known universe not the entire universe. There may be even more. The universe doesn't have a known edge, or a wall so, it's really hard to say. It would be possible to even say infinite, though scientists really hate the word infinite ;)
the universe is bigger than a solar system. Obviouisly, because there are many solar systems in our galexy, and many galexies in our universe, there may be more that one… universe contained in what I choose to call 'Infinity'.
no because if there was a parallel earth there would have to be parallel planets
The age of the universe is in the realm of 14-13 billion years old, and the age of the solar system is approximately 4.56 billion years old.
8 in the Solar System Unknown billions in the universe. There are 8 planets in our solar system and 5 objects identified as dwarf planets. There are at le…ast 81 planets confirmed to be around nearby stars, and another 256 possible plants that are not yet confimred. There is no way of knowing how many planets there are in the universe.
No they are different, the universe refers the whole of space, plants ,stars, solar system galaxy..., where as the solar system is the name we give a single star with planets …revolving around it.
Because it is impossible to determine the extent of the universe because we are only aware of the parts we can see. For this reason, our solar system sits in the very middle o…f the Earth-visible universe. With regards to the rest of the universe, we are almost certainly nowhere near the center.
There is approximately 90 TrillionTrillion (9E25) solar systems in the universe.
there is 1 solar system in spaec ;)
There are an estimated 10 22 - that's a 1, followed by 22 zeroes - stars in the observable Universe. It is not known how much larger the entire Universe is, compared to the o…bservable Universe. Nor is it known what percentage of the stars have planets (to qualify as "solar systems"), but based on recent discoveries of planets, this percentage seems to be rather large.
As we only know of our own in any definite terms we cannot say which is the largest. Nor are we ever likely to be able to do so.
There are on average about 100 billion stars in each galaxy, and 100 billion galaxies in the known Universe, so that means that there are 10,000 billion billion stars in the k…nown Universe (or 10^22 in scientific notation - that's 10000000000000000000000!!) Even if only one in ten of those stars have planets - which is far too low an estimate - there would still be 10^21, or 1000 billion billion solar systems in the known Universe alone - and there are probably an infinite number beyond the boundaries of what we can see!
The universe is all existing matter, energy, space, and time, seen as a well ordered whole known as the cosmos. Believed to be at least 10 billion light years in diameter, con…taining a vast number of galaxies. Said to have been expanding since its creation in the Big Bang around 13 billion years ago.
Univers is everything in existance, solar system is in univers
