Solar = sun, system = planets that orbit the sun
Our solar system is in the Milky Way galaxy.
Galaxy = massive systems of stars, dust, clouds, clusters, planetary systems bound by gravity. A galaxy may contain many solar/planetary systems.
Scientific facts are objective and verifiable through a history of observation from various sources. One person conducting an experiment many times with the same result does not produce scientific fact, others must be able to observe the same experiment with the same results.
Scientific theory is a consistent educated hypothesis, rational model or logical conclusion based on observable data and an unknown variable.

great questions. a solar system is a star that has "stuff" orbiting around it. a galaxy is a bunch of stars and gas and other things orbiting around a central point. there are over a hundred billion galaxies in the universe. WOW!!!! our galaxy alone has about a hundred billion solar systems.
There is no such thing as scientific fact. theories are considered as close to a fact as we can get. theories are the best explination for phenomena that has been observed. for example, newton came up with a theory for gravity, but it was replaced by einstiens theory of gravity because eistein had a "deeper" understanding of just how it works. some people call this fact, but in the future another scientist might get an even deeper understanding and a new theory will replace einstiens. this is what makes science so wonderful, we can change our ideas to fit the observations. meaning we can never say something is a fact!!!!!!!!!!!

A solar system is a group of celestial bodies (planets, asteroids, moons etc, sometimes even other stars, in the case of binary star-systems) that revolve around a star. Example: our solar system (whic is called "the Sol system"), which is a star (our sun) with a load of planets and asteroids going around it.
A galaxy is a LARGE collection of celestial bodies (all of the above), which seem to rotate around an inner point. Some say the middle of a galaxy contains a large black hole, but that is theory. There are VAST areas of nothingness between galaxies, where there are no stars whatsoever. The nearest galaxy to the Milky Way is Andromeda, but I don't rememeber how far away it is (take it from me, its a LARGE distance away).
Scientific facts are scientific theories that have been proven by experiments or discoveries. For a long time, galaxies were only a theory, until they were proven to exist by observing the stars.

A solar system consists of a sun and planets - that's why it call solar.
A galaxy contains many solar systems as well as other astronomical bodies.

Our image voltaic gadget consists of our sunlight, all the planets and different heavenly bodies that revolve around the sunlight. The Galaxy is created from our image voltaic gadget to boot as an amazing many different image voltaic platforms in a configuration many times happening using fact the Milky way. The universe consists of all the galaxies to boot as all the different products shifting approximately in area.

a galaxy is made has billions of stars in it and a solar system is made of a star and planets orbiting around it.

a galaxy is a system with only one or 2 suns with planets (maybe) orbiting them. a Galaxy is a enormous number of solar systems light years across orbiting a black hole or some other kind of object with lots of gravity.
