Welcome to Open SkyQuery!

OpenSkyQuery allows you to cross-match astronomical catalogs and select subsets of catalogs with a general and powerful query language. You can also import a personal catalog of objects and cross-match it against selected databases.

To get started, go the the query page and look at some of the samples.

Please note there are some limitations to this system.
