Stars - Information on the star data in Starry Night

Back to Main FAQ

1. Where does the star data in Starry Night come from?

The star data for the nearest two million or so stars comes from the Hipparcos/Tycho catalogue, which is the result of a recent mission by the European Space Agency. Find out more about this catalog at the Hipparcos Project home page.

2. How do I search for stars in the various star catalogs?

Open the Find pane. For stars in the Hipparcos catalog, type "HIPxxxxx", where "xxxxx" is the star's Hipparcos catalog number. For stars in the Tycho catalog, type "TYCxxxx-xxxx-x", where "xxxx-xxxx-x" is the star's Tycho catalog number.

3. When I zoom far away from the earth, the stars all appear to group together in a ball around the sun. Is this the Miky Way?

No, this is a limitation of our star catalog. Starry Night has distances to about 100 000 stars from the Hipparcos Catalog. Most of the stars in this catalog are within a few hundred light years of the sun, so as you zoom out farther than this, they appear to cluster around the sun.

4. Can I add recently discovered planets around stars other than our sun?

No. A future version of Starry Night may add this feature.
