Aquarius, on the other hand, is a fixed air sign ruled by Uranus, the planet of innovation, imagination, and dramatic change. It’s the second to last sign of the astrological year and is symbolized by the water bearer, representing life-giving spiritual energy. As astrology expert and author of Astrology SOS Imani Quinn tells mbg, given that these two signs share the element of air, “the most immediate thing about their compatibility is that they both process similarly—they’re going to intellectualize things, whether that be their relationships or their own internal processing system.” As the AstroTwins previously explained to mbg, “Air signs bring everyone a breath of fresh air when things start to get stale. Like the breeze, you can’t quite catch them, and you never know where they’ll drop you once they sweep you up.” Beyond their shared element, though, Libra’s and Aquarius’ personalities can be somewhat contradictory. And of course, it’s important to remember that calculating astrological compatibility (aka synastry), requires taking both people’s entire birth chart into account, not just their sun sign. That said, here’s more on how these two signs fare in love and friendship, plus how they’re similar and different. “Aquarians are such humanitarians—they’re always thinking about how they can help everybody,” she explains, adding that Libra energy is helpful for them because it reminds them to re-center and rebalance. “Because if they move too far into thinking about how to help the collective, it’s important that they also make sure their own cup is filled,” she notes. These two signs also share a love for things like art, music, and culture, as well as intellectualizing in general. If friends have mutual interests in these areas, they’ll have plenty to talk about. Just keep in mind that Libra does tend to be more social than sometimes-aloof Aquarius! But just as the element of air can change with the wind, so, too, can the dynamic between these two as lovers. Libra is a romantic and will easily get swept off their feet, only to find they put their lover on a pedestal. Aquarius, meanwhile, has a cooler approach to dating and may back off if someone gets “too close.” That’s not to say these patterns are bound to play out, but as Quinn notes, it’s possible. On the other hand, though, if both people are showing up as healthy and mature individuals (who don’t compartmentalize and intellectualize every emotion), they have rich potential to connect on deep, value-based levels that will nourish the relationship. And keep in mind that while sharing the element of air will aid in things like conversation, mental stimulation, and even humor, both signs have a tendency toward feeling ungrounded. According to Quinn, “Everything is going to be heady for both of them, so it can even be challenging to be connected to their emotions,” adding that Libra will typically play peacemaker and try to figure out what’s wrong. In this way, they make a great tag team for thinking about cultural movements, social justice, and working together, she explains. And as aforementioned, they also both have a strong capacity to align through cultural things, whether it be art, music, and even networks of people. In some contexts, Libra may also be over-accommodating if they feel that telltale Aquarian coolness creep in. Libra often strives to maintain peace and harmony at all costs (even if that cost is their own peace), Quinn explains, and may naturally want to overcompensate if Aquarius becomes aloof. Again, these patterns may not always take place, but it’s something to be aware of if one or both people are exhibiting these common astrological traits.
