Exoworld is a free, open-access astronomical database built on observational data from the Gaia space telescope, the JPL Small Body Database, and the HYG stellar catalogue. Every object carries a unified Franklin Galactic Star Catalogue identifier — a hierarchical positional reference system anchored to the galactic centre.

This is not a visualisation tool. It is a database — built for researchers, educators, and serious amateur astronomers who want access to complete, consistent stellar data without institutional barriers.
