The eleventh brightest star in the sky has a celestial feel, but also could be the name of a commercial airline.

Astrological name retains a hippielike Age of Aquarius feel.

Aquarius

An evocative ancient word that's used as a first name in the New Testament, among other places. It's also the name of an eagle-shaped constellation. 
That said, contemporary interest in the name Aquila probably stems from its use as the name of Facebook's secretive drone project. If that takes off, and its name doesn't change, Aquila could take a hit, like Siri and Alexa before it.

J.K. Rowling is a modern master of naming who brought a whole constellation of ancient and celestial names to modern parents. Bellatrix, of one of the stars of Orion, combines fashionable names Bella and Beatrix to make a convivial and original name. The down side: the Harry Potter character Bellatrix, played by Helena Bonham Carter, is a character so evil she's called a Death Eater, killing one beloved character and being murdered by another. And the name Bellatrix is so closely associated with that character that it might be challenging to sidestep the association.

Capella, the eleventh brightest star in the sky, carries much mythological and astrological significance.  In Roman mythology, Capella represented the goat that suckled Jupiter, whose horn became the Cornucopia or horn of plenty.  In Hindu mythology, Capella is called the heart of Brahma, while English legend calls it the shepherd's star.  Australian Aboriginal myth calls it the kangaroo, while in Persian mythology it's a metaphor for both great distance and the color light red.  Astrologically, Capella symbolizes wealth and military honor.  As if that wasn't enough, CapPella (two p's) also has a musical reference to a cappella singing.

Cassiopeia, the name of a mythological mother who became a stellar constellation, is challenging but intriguing, and has all those softening Cass nicknames available. And with all names Cass-related trending, Cassiopeia may be an unusual route to a stylish name.

With the rise of other otherworldly and mythical choices, from Apollo to Jupiter to Juno, Cassiopeia may just feel more possible for mortals now than ever before in its long history.

Some sources say the meaning relates to the cassia berry or tree, and may be "cassia juice," making this a botanical as well as a mythological name.

Cassiopeia

Celestia is a heavenly name that sounds more ethereal than Celeste, Celestia might make a distinctive, feminine choice if your taste runs toward names like Angelina and Seraphina.
 Celestia was more popular than you might think in the late nineteenth century -- it made the popularity list six times in the 1880s. Celestia was the middle name of Caroline (Carrie) Ingalls in "Little House on the Prairie."

Corona was once an improbable choice due to the beer brand. After the coronavirus pandemic of 2020, its firmly cemented its status as a nonviable baby name.

We all heard it on Seinfeld as the long-concealed first name of Kramer, then considered a punchline. Now some pioneering parents are embracing this expansive Greek name, which makes a creative and cool choice for a baby. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, which will likely drive Cosmo up in popularity. In the UK, it currently ranks within the Top 1000 boy names and is trending upwards.

 In literature, Baron Cosmo Bradwardine is a character in Sir Walter Scott's novel Waverly and Cosmo Topper is the befuddled banker in Thorne Smith's humorous novel Topper. In modern times Cosmo has become the short form for Cosmopolitan – both the magazine and the cocktail. And for those wishing to honor a medic in the family, Cosmo is also the name of the Arabian-born patron saint of doctors.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.
 
The name of the supreme Roman deity and the largest planet has until recently had either too hippie or too grandiose a feel for most mortals, but with the rise of sound-alike Juniper and space names such as Orion and Mars, Jupiter may find new favor.
 
Short form Jupe is adorable.
 
More background on that deity: Jupiter was the king of the Roman gods, and god of the sky, the equivalent of Greek Zeus. His name may have originated as a title. It can be interpreted to mean "father of the sky" or "father of the gods" (dyew-peter > iou piter > iuppiter (the form of the name used in Latin) > Jupiter). With Juno and Minerva, he made the Capitoline triad, whose worship was at the very centre of Roman religion.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Derived from the Latin meaning "lion", Leo is one of those names, like Luke and Finn, that many people assume must be short for something but that is authentically a complete name in its own right. That said, Leo can but short for any number of names, from Leonardo in Latinate languages to Leon and Leopold in Germanic languages. We've even heard of little girl Leonoras and Leonies called Leo: How cute is that?

Leo's simplicity makes it an international star, ranking in the Top 100 in countries as diverse as Ireland and Israel, Spain and Sweden, Austria and Australia. Leo is a truly diverse name, a perfect choice for any family crossing countries or blending cultures.
 
Leo's only real downside is its universal popularity and familiarity. If you call your child Leo, you and they will almost certainly encounter many other Leos over the years of all types and ages. Plus or minus? Or both?
 
Penelope Cruz and Javier Bardem called their son Leo, as did actress Kim Raver, NASCAR driver Jeff Gordon and Kristin Olson. 
 Famous Leos of the past include Pope Leo the Great, a number of early saints, and Leo Tolstoy, as well as Dead End Kid Gorcey, colorful baseball manager Durocher, influential gallerist Castelli and the leonine MGM icon. There have been Leos seen on everything from The West Wing to Charmed to Grey's Anatomy to Seinfeld's Uncle Leo.

Appropriate for a girl born between late September and late October, Libra suggests both balance and freedom.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.
Often ranked as Number 1 on Nameberry's internal charts, the strong but shimmery Luna is among the Top 100 names for baby girls in a wide range of countries around the world, from France to Italy to Germany, Scandinavia to Slovenia to Spain. It's simple, easy to spell and pronounce, and remarkably diverse.
 And it's also got deeper roots than you might imagine. It was somewhat popular in the US as a baby name around the turn of the 20th century, reaching a high of Number 403 way back in 1881.

Luna's popularity is undoubtedly influenced by the Harry Potter character Luna Lovegood and several high-profile celebrity babies, notably the oldest daughter of Chrissy Teigen and John Legend. 
 Along with its celebrity connections, Luna's popularity is partially driven by its standing as a mythological name. Luna’s divine complement is Sol, the god of the Sun. In Roman art, Luna is often depicted driving a chariot.
 
Luna makes another appearance as the endearing oddball Luna Lovegood in the Harry Potter series, who was central enough to the story to have Harry give his daughter Luna as a middle name, and as the True Blood teacher-shapeshifter character, Luna Garza. 
 
Along with Chrissy Teigen and John Legend, other celebrities who named their daughters Luna include Penelope Cruz and Javier Barden as well as Constance Marie. Joely Fisher and Ellen Pompeo have used it as a middle. Uma Thurman and Arpad Busson use Luna as the nickname they call daughter Rosalind Arusha Arkadina Altalune Florence.
 
Luna is also among the <a href="https://nameberry.com/popular-names/dogs">most popular dog names</a>.

Lyra is a name with ancient and celestial roots that's finding new popularity thanks to its starring role in Philip Pullman's His Dark Materials series, seen in the movie The Golden Compass. Simple yet unique, Lyra hits the sweet spot between too popular and too unusual.
 
Lyra is a constellation name taken from the lyre of Orpheus. It contains the star Vega and thus could make a melodic choice for a parent interested in music, astronomy, or mythology. It has more depth and history than Lyric, is more unusual than Lila (which it rhymes with). It debuted in the US Top 1000 in 2015.
 Lyra was chosen for their daughter by Ed Sheeran and Cherry Seaborn, as well as Sophie Dahl and Jamie Cullum. And then there's Lyra Belacqua, the heroine of His Dark Materials and The Golden Compass.

The name of the Roman god of war began to sound less intimidating when Erykah Badu gave it to her daughter, and musicians Thomas and Bruno Mars (the latter born Peter Hernandez) have given it a modern edge. Mars actually could make a pleasant, planetary middle name for either sex.
In Roman mythology, Mars was the god of not just war, but also agriculture, and was more down-to-earth and less cold and ruthless than his Greek counterpart Ares. He was considered a father of Rome, as he was the father of mythical founder Romulus.

Orion is a rising star, with both mythical and celestial overtones.
 The Greek mythological Orion was the legendary hunter who pursued the seven daughters of Atlas, was slain by the goddess Artemis, and then placed as one of the brightest constellations in the night sky by Zeus.
 Mark Twain had a brother named Orion, and Chris "Big" Noth picked the name for his son. It is also a Harry Potter name.
 Orion's Gaelic connection to O'Ryan/Ryan makes it familiar as well as unusual.

Yes, it's the name of the brightest star in the sky, but can't you just hear people saying, "Are you serious?" Singer Erykah Badu used it as a middle name for son Seven.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina. 
 
The name Stella was derived from stella, the Latin word for “star”. It was coined by the poet, Sir Philip Sidney who used it in his 1590 sonnet collection, Astrophel and Stella, which translates literally to “the star lover and his star.” 
 
While Astrophel has remained obscure, Stella came into common usage in the 1800s. Inspired perhaps by its similarity to Ella and Esther, and by its association with the Virgin Mary, from her Catholic title, Stella Maris, it was popular in the early decades of the 20th century.
 
After fading in the 70s, Stella is now back and brighter than ever. Following on the heels of Gabriella and Isabella, it ranks in the US Top 50 and is given to almost 5000 babies each year. With equally astronomical Luna now making the Top 10, Stella might rise even higher.
 
Stella holds international appeal too and has taken shining spots on the charts in Switzerland, Sweden, Australia, Italy, and France. 
 
The name Stella was famously bellowed by Marlon Brando in Tennessee William’s A Streetcar Named Desire, and it has proved a popular choice among celebrities, including Matt Damon, Ellen Pompeo, Tori Spelling and Dean McDermott, and Gena Lee Nolin. 
 
Designer and animal rights activist Stella McCartney is another notable namesake, as is Stella Adler, an influential acting teacher. 
 
If Stella is shining for you but it’s not quite the brightest star on your list, then you could consider its variants, the literary Estella, or the French Estelle. Alternatively, you might like another starry name, such as Astraea, Seren, or Izara, or something just equally celestial, like Elara, Celia, or Celeste.

Ursa might be a good choice if you're looking for a bear name for your daughter but want to avoid the She Witch curse placed on Ursula by Disney's The Little Mermaid. Too bad, because Ursula is a classic and lovely name, but Ursa has less baggage.

Ursa

Another astral name, this one relating to one of the largest and brightest stars in the heavens, is popular in Scandinavia and Spain, where it ranks among the Top 50 <a href="https://nameberry.com/girls-names">girls' names</a>. Although still very rare in the US, we think it has serious potential to follow the likes of Luna and Lyra up the charts.

 In Spanish, the name means "meadow" and is taken from a title for the Virgin Mary (La Virgen de la Vega, The Virgin of the Meadow).

Vega

The name of a heavenly planet and the Roman goddess of beauty and love was an intimidating no-no until tennis champ Venus Williams put an athletic, modern spin on it. 
 
Associated with the Greek Aphrodite, in the Roman pantheon, Venus (whose name probably means "desire") was considered the mother of the Roman people and has always been a favorite subject of artists — most well-known being the prehistoric sculpture Venus of Willendorf, the ancient Venus de Milo and Botticelli's The Birth of Venus.
