About the Map

This map is a plot of the 1500 most luminous stars within 250 light years. All of these stars are much more luminous than the Sun and most of them can be seen with the naked eye. About one third of the stars visible with the naked eye lie within 250 light years, even though this is only a tiny part of our galaxy.
Additional Maps
A map of solar neighborhood stars There are 133 stars visible with the naked eye within 50 light years of us, and here is a map showing all of these stars.
Data and Catalogs
Stellar Classification Here is a concise diagram showing most of the different types of stars that exist together with some basic data on sizes, masses, temperatures etc of all the different star types.
The HR Diagram All of the major types of stars have a location on the Hertzsprung-Russell diagram which is a plot of the luminosity of stars against their colour.
A list of the Brightest Stars This is a list of the 200 brightest stars together with the distances taken from the Hipparcos catalog.

The Hyades Star Cluster

The Hyades cluster is the nearest major star cluster and the only one close enough to be mapped in three dimensions. The Hyades cluster is a bright object in Taurus, but the view is partially ruined by Aldebaran - a brilliant orange giant star that lies in front of the cluster at less than half the distance. The cluster itself is 151 light years away. It was formed about 660 million years ago and the cluster has probably gone around the Galaxy three times since then. Like most open star clusters, the stars in the cluster are slowly moving apart.
