Distance of our Solar Neighborhood

Major objective of this lecture is to present on distance of our Solar Neighborhood. Knowing the distances to our stellar neighbors can help us learn more about the stellar neighborhood. The distances to the stars in our solar neighborhood will change over time, because the stars are not stationary. The Solar Neighborhood is the stars within about 15 light years of the Sun. Most nearby stars are red dwarfs: cool M-type main sequence stars. The Sun is part of the Milky Way Galaxy, a system of more than 200 Billion stars, made up of a disk and central bulge.
