exists and is an alternate of .

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 100,000,000,000 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 ;)
