Astrolog 7.20: Free and open source astrology software

• Display all standard objects, along with any number of asteroids, dwarf planets, or other minor bodies.
• Planetary moons are a rich new development in astrology! Astrolog is the first astrology program to support moons of other planets.
• Dozens of house systems, including newer ones like 3D houses, sinusoidal houses, and balanced equal houses.
• Transits: Display transit lists, transit calendars, and orb graphs over time.
• Eclipses: Detect and graphically animate solar eclipses, lunar eclipses, and eclipses involving planetary moons.
• Graphical atlas with automatic time zone and Daylight Saving Time detection.
• Astrocartography: Display 2D maps, 3D globes, and even minor cusps.
• Space is 3 dimensional, and astrology should be too! Astrolog supports standard 2D wheel charts, and also 3D "chart spheres".
• Astrologers know the difference between signs and astronomical constellations. Astrolog can display and contrast both together.
• Astrology can be a tool for spiritual growth. Astrolog has a number of Esoteric Astrology features.
• Astrolog is 100% free, and even open source if you have programming knowledge and want to inspect or even modify its source code.
• Don't want to download anything? Astrolog or at least a subset of its features can be run in a browser on various sites.

• Improved wheel charts, with options for filled in areas (with rainbow colors or other patterns), line thickness, different text fonts, and decan markings, such as seen above.
• 6 chart hexa-wheels, for when quad-wheels with 4 charts at once aren't enough!
• Planetary visibility chart, showing when selected planets are above the horizon during the year.
• Rings of Uranus can be displayed in Astrolog's telescope/planetarium chart. (Astrolog already supports Saturn's rings.)
• Space probes and other additional objects. For example, the Astrolog animation below shows the five spacecraft which have exited our solar system so far (Pioneer 10&11, Voyager 1&2, and New Horizons):
