14-sign sidereal astrology system
Posted: Sun Mar 02, 2025 2:50 am
Good morning/afternoon.
My name is Joseph D. W. Pelobello and I have been interested in natural sciences (geology, astronomy, etc.) since I was young, but I have been into astrology recently. However, upon learning about the difference between traditional tropical and sidereal astrology, I began noticing that sidereal astrology would be a better fit for me—and it also seems to describe most people I know a lot better.
While researching this, I came across two books written by Steven Schmidt in the 1970s: Astrology 14: Your New Star Sign and The Astrology 14 Horoscope: How to Cast and Interpret It. Steven Schmidt not only updates the existing signs to match more closely with the dates where the Sun currently crosses over the constellations they were based on, but also adds two more signs also in the zodiac band: Cetus and Ophiuchus. This leads to a total of fourteen signs.
There are some things I want to point out and summarize from the books:
Here are all 14 signs and the ruling planets assigned to each of them:

There are some things I want to point out and summarize from the books:
- Schmidt's motivation for writing the books stems from him wanting to make astrology a legitimate science. He wants astrology to be open to new ideas and change with the times, as mainstream science does.
- Each sign occupies roughly 25.7 (360/14) degrees along the ecliptic and is in equal length. There are also 14 houses, instead of 12, as a result.
- Because of the above two points, Schmidt drops the usage of classical elements in his system, along with decans and the midheaven. His books also don't seem to have any mention of exaltations (although page 44 of his first book still implies a solar exaltation in Aries).
- As expected, Schmidt uses modern rulerships, in dire contrast to most sidereal astrologers I've seen who are more strict on using traditional rulerships.
- Schmidt keeps the traditional aspects and their meanings.
- Schmidt wanted to use the scientific method to find the typical traits for each star sign: he sampled a very large number of people falling within a sign (including famous people and people he knew personally) and tried to determine each sign's trait by finding common traits within those people. Hence, some of the traits he describes for each sign could be different from what traditional astrology teaches.
Here are all 14 signs and the ruling planets assigned to each of them:
