Asteroids are an interesting way to connect with mythology, but I wouldn’t give them too much weight astrologically in a natal chart. Nevertheless asteriods are great fun to play with and I do find them synchronistic at times. When using asteroids the orbs must be very tight, not more than 1º orb, and really only relevant if the asteriod is conjunct the Sun, Moon or the angles. If you find yourself strongly attracted to a mythical figure it is worth looking up the asteroid name and see if it features strongly in your chart.
Ceres, Pluto, Eris, Sedna, Chiron and the Black Moon Lilith I still find relevant so I continue to leave them in natal chart readings and bring them up if they feature strongly. My reasons being the first three are dwarf planets and connected by the Persephone Myth, Chiron is a bit special in that he is classified as a comet, Sedna is just a fascinating myth to me and the Black Moon is the lunar apogee. The rest of the asteroids and minor planets are loosely categorised into three sets:
• Main Belt Asteroids, the Greco-Romans between Mars and Jupiter like Juno and Vesta.
• Trans-Neptunians (TNO’s), not all technically asteroids and some large enough to be minor planets like Sedna and Orcus.
• Centaurs, all small TNO’s like Pholus and Nessus, except Chiron who orbits between Saturn and Uranus and is actually classified as a comet.
ASTEROIDS & PLANETS
Finding Asteroids In Your Chart
1. Create your free chart at astro.com HERE.
2. Choose “Extended Chart Selection”.
3. Select everything in the “Additional objects” box. This will show the major asteroids in your chart.
4. If you have a particular asteroid in mind that is not in that additional objects box, then under that you will find a box called “additional asteroids or hypothetical planets”. Find the number of the asteroid you want from this Asteroid name/number List and add it to the box.
5. Yet another option is to use Serennu to list over 1000 asteroids in your chart. Remember to use UT for your time of birth, select “sort by degrees of the zodiac“, add the coordinates of your birth place, then select “Include first 1,000 asteroids“.
The Wikipedia Asteroid Name Meanings Page lists all the known asteroids by number with links to the deity, person or place they were named after. It’s important to also consider the personality of the planetary body through it’s orbit, appearance and it’s discovery chart as well as the myth behind it. I would suggest browsing through Zane Stein for the TNO’s, Juan Antonio Revilla and Zsuzsanna Griga for Centaurs.
