Asteroids are a fun addition to your astrology learning once you've mastered the planets. There are thousands of them (currently over 20,000!), so it's impossible to know and use them all, but they can be interesting. You can look them up in your natal chart and you can track them like a transit planet.
One set of asteroids you can look into are the asteroids that are just names. Lots of asteroids are just names, named after those who discovered them or others. You can find the asteroids of your first, middle, or last names, or of your nicknames, and they can almost operate like an alternate Sun.
You can use these in love astrology analysis too! By using the asteroids for your name and the asteroids for the name of your beloved.
Asteroids of Your Name Transits & Love
When the transit asteroid of the name of your beau aspects your natal planets, or the transit planets aspect your natal asteroid of your beau's name, this can show developments and higher energy with them, good or bad. Hard aspects (squares and oppositions) may show fights (especially with Mercury, Mars, Uranus, or Pluto), or dealing with them may be more of a challenge (like they're more distant with Saturn or Neptune, too unstable with Uranus, too stubborn with Venus, a little demanding with the Sun).
Beneficial aspects (sextiles and trines) can show happy developments between you, and can be good times to further the relationship and take next steps (like moving in together or getting married), to go on dates or vacations together, or anything else that's just a pleasant thing between you. The energy can be easier for simply getting along.
I often find that when someone comes into your life, an asteroid of their name is prominent for you at that time. It may be that the transit asteroid of their name conjuncts one of your natal planets or angles, or that there's a progressed aspect involving the asteroid of their name, or an eclipse. Or it may be reversed, and the asteroid of your name is big for them. But usually, when it's important for both of you, then both of you will have it!
Asteroid of Your Name & Synastry
No surprise, but there's usually some strong synastry with the asteroids of yours and their names as well. They may aspect one another in your natal charts; the asteroid of one person's name conjuncts a natal planet or angle or Lunar Nodes in the other person's chart; the asteroid of one person's name makes lots of aspects to the other person's natal chart; or the asteroid of one person's name fills a hole in the other person's chart, like occupying the empty leg of a t-square or being in the missing sign of an element to form a grand trine.
By itself, the name asteroids may not show that much, but if someone's name is important in your natal chart, they are likely going to show up at some point. This may just get triggered by transits and progressions and actually bring that named-person into your life.
