Stars API

The Stars API provides key statistics for thousands of stars discovered in the known universe.



Get a list of stars matching specified parameters. Returns at most 30 results. To access more than 30 results, use the offset parameter to offset results in multiple API calls.


At least one of the following parameters other than offset is required.

name (optional) - the name of the star. Note that many of the star names contain greek characters.

constellation (optional) - the constellation that the star belongs to.

min_apparent_magnitude (optional) - minimum apparent magnitude brightness of the star.

max_apparent_magnitude (optional) - maximum apparent magnitude brightness of the star.

min_absolute_magnitude (optional) - minimum absolute magnitude brightness of the star.

max_absolute_magnitude (optional) - maximum absolute magnitude brightness of the star.

min_distance_light_year (optional) - minimum distance the star is from Earth in light years.

max_distance_light_year (optional) - maximum distance the star is from Earth in light years.

offset (optional) - number of results to offset for pagination.


X-Api-Key (required) - API Key associated with your account.

If your programming language is not listed in the Code Example above, you can still make API calls by using a HTTP request library written in your programming language and following the above documentation.
