User-defined stars

Now you can define up to eight custom points in space that have a fixed heliocentric right ascension, declination, and distance. These are called user-defined stars, although they don't literally have to be stars. They can be any object that is more than one light-year away from the Sun.

To create a user-defined star, call the function for your language:

• C/C++: Astronomy_DefineStar.
• C#: Astronomy.DefineStar
• TypeScript/JavaScript: DefineStar
• Python: DefineStar
• Kotlin/Java: defineStar

Once you have associated a custom star with a Body value, you can pass that value to functions like SearchRiseSet, GeoVector, etc.
