Hey, I am new to Mathematica; just got my copy a couple days ago. I have been trying the Astronomical Computation and Data routines using examples from the docs, but many of them don’t return data. This is typical:
I’ve read that “PlanetData”, etc., have replaced “AstronomicalData”, but “AstronomicalData” returns real data. This happens with other routines, like “MineralData”.
I’m not able to reproduce the problem. It might be some kind of fluke. Both of these should work.
I would first try following this article which walks you through resetting your installation to its default settings:
I know you might not think you’ve done anything to warrent going through this, but you likely have downloaded paclets by evaluating functions so it’s worth a try.
If you are still seeing issues, I would contact Wolfram Technical Support (support@wolfram.com).
