Do other galaxies have solar systems?

Answer 1

The definition "Solar System" is defined as the Sun (Sol) and all the objects in orbit around it, but also a collection of heavenly bodies including a star or binary star, and any lighter stars, brown dwarfs, planets, and other objects in orbit.

To ease confusion, "Solar System" is generally our Sun and the objects that orbit it. For other "Systems" use planetary systems [See Link]

For a list of known planetary systems and known extrasolar planets, see link.

Outside of our Sun there are over 400 planets known to orbit other stars and the number is increasing every day.

So yes there is other "solar" stellar systems in space - probably billions of them, but as yet we only know of a few.

Answer 2

That is almost certainly the case. We are finding several other solar systems right here in the Milky Way, and we've only just begun walking a little down the galactic street. And the Milky Way is a very big place. It seems unimaginable that whole galaxies could exist that do not have a fair share of solar systems. It's very important to keep in mind that we do not know the real probability that a given solar system sustains life. Ours is the only one we know of at present. But it is beginning to appear that there are huge numbers of solar systems throughout the universe, and our ability to find and study them is increasing all the time.

Answer 3

Yes there are billions of solar systems in this univerese. Some having only one planet, others with more than 8 planets ! Some having a single star while the others having more than one stars!!

Answer 4

Apart from our own solar system, we have so far discovered at least 53 other planetary systems. It si suspaect that most stars may have planets (and thus are solar systems) which would mean that there are countless billions of solar systems.

Answer 5

The term "solar system" can be confusing now that we know there are many of them. Often, "the solar system" refers to our local system, the one containing earth. But generically, any star that has celestial bodies orbiting it can be thought of as the center of a solar system. In that case, all or most of the stars in the galaxy would be part of solar systems. They do not all contain orbiting planets as ours does, but many of them do; hundreds of planets outside of our solar system have been discovered, and we have just begun.

Answer 6

Others have been discovered, but that dosnt Mean that they contain life

Answer 7

As of now ... early 2012 ... the Kepler Space Telescope has collected evidence

of something like 700 planets orbiting stars outside our solar system, and the

count continues.

Answer 8

Yes, galaxies are comprised of billions upon billions of solar systems.

Answer 9

Yes, every star that has planets circling it is a 'solar system'.

Answer 10

More than likely!

Some of the stars seen, forming the galaxy, will also have planets.
