Our sun is a star, right?
How many suns like ours are there?
7.5 billion to 30 billion.
We surmise that in the Milky Way Galaxy, there would be about 10^8 single M stars like our sun. However, we can't be sure as there are many globular clusters that contain stars much like our sun.
Most stars in our galaxy are binary stars (and a few 3,4, and 5 star systems). Centauri for example is made of Proxima Centauri, Alpha Centauri, Beta Centauri, and Dista Centauri. These four stars were once thought one larger star until we found irregularities in the radiative spectra indicating four stars in the group.
This is the closest stellar neighbor, and it is far too distant to reach it.
