Astrolog [astrology software]

https://www.astrolog.org/astrolog.htm

Astrolog 7.20 is a 100% freeware astrology program, with versions for Windows, Unix, the Macintosh, and the complete source code is available too.

Astrolog shows graphical ephemeris, identifying aspects of planets and other celestial objects.

Would make a great addition to the portableapps stable.
