It is hard to say what is "typical", since galaxies vary quite a lot in size. Our galaxy has between 100 and 400 billion stars; some other galaxies are larger, but there are also lots of dwarf galaxies, some of which have only a few million stars. A typical spiral galaxy, like ours, has a few hundred billion stars.
galaxy - it is a cluster of many million stars universe - it is acluster of many million galaxies
I dont knoe You tell mee
A large group of stars is called a galaxy. Many people believe that it is a constellation but that is a group of stars that for a perticular picture. +++ I'd say "cluster": a galaxy consists of a huge mass of many millions, or thousands of millions, of individual and clustered stars, and clouds of gas and dust.
The Milky Way has somewhere between 100 and 400 billion stars; most of those are red dwarf stars.
The best estimate of the number of stars in a typical galaxy is unknown there is so many but the best estimate is BILLIONS
Our galaxy, the Milky Way, has somewhere between 100 billion and 400 billion stars (it's difficult to estimate precisely). However, it's not really "typical"; it has more stars than any other galaxy in the "Local Group" except for the Andromeda Galaxy, which has about a trillion stars. I'm not sure there really is such a thing as a "typical" galaxy.
i believe my teacher said around 200,000
Well, the phrase "typical galaxy" begs a debate in itself (smile), but the most commonly heard figure for "stars in a typical galaxy" is 100 billion. And many astronomers believe there may be 100 billion galaxies in the known universe. The math gets kind of heavy duty!
A typical galaxy may have anywhere between a few million (106) stars, and over a trillion (1012) stars. Our own Milky Way is estimated to have between 200 and 400 billion (2x1011-4x1011) stars.
Sizes vary, of course. A typical size is a few hundred billion (10^11) stars; some of the larger ones can have more than 10^12 stars. Our galaxy is a barred spiral galaxy and it has somewhere between 200 and 400 billion stars. Andromeda is an even bigger spiral galaxy. I could not say how many stars the smallest spiral galaxy would have, or how many the largest. There are cases where two spiral galaxies are colliding.
They make reasonable estimates, based on the number of galaxies, and the size of a typical galaxy.
they estimate how many stars the galaxy has: by measuring the size and brightness of the galaxy
If there weren't so many stars it wouldn't be a galaxy, probably a cluster.
Out galaxy contains an estimated 200 billion stars.
There are billions of stars, planets and moons in a galaxy.
