The Variable Star Index is the largest amateur-led project to catalog and detail every variable star known in the Galaxy. It was launched in 2005 by importing as many catalogs of variable stars as were available. Since then, the number of sky surveys and new variable star discoveries has grown, as have the number of amateur and professional researchers finding new variable stars. In eleven years, VSX has grown to a catalog of almost 400,000 variable records.
