We don't have an accurate overview of all the stars in the Milky Way - even the total number of stars may be anything between approximately 200 billion and 400 billion. However, many stars are part of double or multiple system, so we can be fairly sure there are millions of triple stars, just in our own galaxy.
Scientists estimate that there are around 58 billion star systems in our Galaxy.
90%.
Yes. It's impossible to list all 180 billion star systems in the Star Wars galaxy.
If you counted 1 number per second, it would take 5700 years to count all 180 billion star systems in the Star Wars galaxy.
The Star Wars galaxy literally contains millions of inhabited systems.
Polaris (the North star - Alpha Ursae Minoris) is a triple star system, but appears to us as a single star. Alpha Centauri is also another triple star system. And there are many more.
A triple star system.
A star is one, a galaxy is many.
Galaxy! A galaxy contists of billions of star systems .. A nebulea on the other hand just contains the raw ingredients to make a star in a very dense cloud.
A galaxy is made up of all sorts of matter, including stars. Many stars have object orbiting them, such as planets, asteroids, and even other stars. Solar systems orbit the galactic centre of a galaxy. (Solar systems don't orbit a galaxy, they ARE the galaxy)
A good rule of thumb: Of the stars in the sky 1/2 are in double star systems Of the double stars in the sky 1/3 are in triple star systems Of the triple stars in the sky 1/4 are in quartenary systems ad infinitum It's not precisely correct, but uncertainty in these numbers are so large that it is within the error bars.
Current observations seem to suggest that about 50% of all stars are multiple star systems
