Best Regards, H.F. 1. One of my future goals someday is to become an astronaut and the mysteries that it holds encourages me to keep this dream alive. One draw back however is the speed that the shuttle moves. Our galaxy has about 100 billion stars. There are lots of different ways.
None are very precise.
This can only be done for fairly nearby stars. By comparing the brightness of the stars in the distant galaxy to the brightness of the same type of stars in our own galaxy, we can get the distance. Most of the objects you can see with your plain eye are stars in our own galaxy. Each contains only a few billion stars. In the northern hemisphere, you can make out our nearest big neighbor, the Andromeda galaxy, if you know where to look.
