Tycho 2 Star Data
Launched in August 1989, the Hipparcos satellite successfully observed the Milky Way Galaxy for 3.5 years before operations ceased in March 1993. Calculations from observations by the main instrument generated the Hipparcos Catalogue of 119,218 stars, charted with the highest precision. That catalogue is used for the Star Data demo cube installed with Antaeus.
An auxiliary star mapper pinpointed many more stars with lesser, but still unprecedented accuracy, in the Tycho Catalogue of 1,058,332 stars. The Tycho 2 Catalogue, completed in 2000, brings the total to 2,539,913 stars, and includes 99% of all stars down to magnitude 11, almost 100,000 times fainter than the brightest star, Sirius.
This cube contains most of the Tycho 2 data and is intended to provide you with experience in navigating very large cubes. You need not have any knowledge of astronomy to appreciate the way information is presented by this cube.
To view this cube, we recommend that you have a minimum of 2GB memory and a Duo Core 1GHz processor. If your system is specked better than this, then you shouldn't have any problems.
