Galaxies ARE groups of stars. Lots of stars though. Not just like 2 or 3...
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Galaxies are vast collections of stars. So I guess you could say that a big group of stars forms a galaxy. Our galaxy has many big clusters of stars within it, so not all star clusters are galaxies. If you have a cluster of several million or billion (or trillion) stars surrounded by a lot of empty space, that is probably a galaxy.

Milky way!
The other planets, stars, galaxies, meteors, comets, and asteroids.
Stars, planets, moons, comets, asteroids and other phenomena.
No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.
Groups at different scales (from smaller to larger) are called:* Multiple stars (two or more stars that are gravitationally bound) * Star clusters * Galaxies * Galaxy clusters * Superclusters
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
All stars and galaxies are in the universe.
The answer is portons and neutrons nonetheless join up together and make a bang then they are formed into galaxies and stars.
Elliptical galaxies may vary in shape form but are spherical or flattened disk-shaped galaxies (large groups of stars). See related link for a pictorial.
