Welcome to Project AstroFly

AstroFly is a software project, which is intended for educational use; thus, if you are interested in astrophysics, it may help you to expand your knowledge about our Universe. Its main purpose is to present the three-dimensional models of our neighborhood in our own Milky Way Galaxy on a personal computer. The 3D models are based on the remarkable Hipparcos and Tycho Catalogues, which are the products of the European Space Agency's Hipparcos Space Astrometry Mission.

Because of the "CAD-style" approach explained in the next section, an observer is not bound to our Earth in this software; moreover, the Earth itself and all other non-stellar objects are not concerned by AstroFly.

Project's History

After we had obtained the Hipparcos and Tycho Catalogues in 1998, we started to import the 3D coordinates of stars into a Computer Aided Design (CAD) system in order to create a 3D visual model and to enjoy the so called "fly-through" feature. Because any change in a set of displayed stars required a new process of converting and importing data into a CAD system, we decided to develop a special application, which would be able to filter stars dynamically by many parameters and provide some useful features of CAD systems.

Although the development is very complicated and slow (the biggest troubles are described in the AstroFly Help), the current version of AstroFly contains a lot of interesting features, and we hope that some new ideas will follow. Currently, we are trying to develop a new edition of AstroFly-- AstroFly Galactic Edition.


  • You can fly anywhere in space.

  • Each star is depicted with its "real" color.

  • You can filter stars by many parameters.

  • Simplified Wireframe of Our Milky Way Galaxy is available.

  • You can check a star in the Hertzsprung-Russell diagram.

  • Finding a famous star by its names is available.

  • You can study constellations.

The current version of AstroFly consists of two packages. The AstroFly 3.0 Basic Package contains installation of the AstroFly's executables and the star database derived from the Hipparcos Catalogue; the AstroFly 3.0 Plus Package, installation of the star database derived from the Tycho Catalogue.

If you want to use the AstroFly 3.0 Plus Package, it must be installed into the same directory as the AstroFly 3.0 Basic Package.
