The Astronomy Plugin provides celestially accurate positions of astronomical objects, including the sun, moon, stars, and planets.

Example applications include:

For advanced users, the Plugin also has over 30 advanced astronomical functions accessible through Blueprints, and can use three kinds of planet ephemeris: JPL Low precision formulas, VSOP87, and high-precision NASA bsp files.

Additional Notes:

The core of the Plugin is a static Blueprint library of over 30 astronomical functions. The Plugin is designed to integrate with your Blueprints and artwork, the star and planet Blueprints that come with the Plugin are low quality and intended for demonstration purposes. It is not recommended to use a SkyBox if you are placing star and planet actors – those objects will be in front of the skybox, so the stars and planets will appear in front of skybox clouds.
