Space and Star Themed Names for Your Baby


Here is a list of beautiful boy and girl (and unisex) names to give your baby:


Phoenix is the name of the spacecraft that was sent to Mars for investigation. Phoenix means “deep red”. Phoenix is also the name of an immortal and mythical bird mentioned through many cultures that lives up to thousands of years of age before erupting into flames, from the ashes of which it rises again.


Jupiter is the name of the king of the pagan roman gods, and he is the master of the skies. Jupiter was considered to be able to control lightning and the weather at will. It is a cool name for boys as they will love the mythological association with it.


Jupiter is also the name of the largest planet in our solar system. This name kind of ticks all boxes, right?


Pluto, similar to Jupiter is also derived from the name of a roman god. Pluto, in fact, was the older brother of Jupiter, and the king of the Underworld. It has a sort of dark theme to it, which your son will probably soon grow to love and appreciate, because, c’mon, Lord of the Underworld has to be one of the coolest titles ever, right?


The comet Holmes was once the largest known object in the solar system. It’s also associated with Katie Holmes and Sherlock Holmes (already a BIG win there). They have Holmes as a surname, but Holmes would make an equally good first name or middle name, don’t you think?


Orion was originally the name of a great Greek hunter. He was a demigod, son of Poseidon, and has been mentioned several times throughout Greek mythology as one of the greatest warriors of his time.

Orion the constellation, also called The Hunter, is the brightest and best-known constellation in the sky. This constellation consists of three conspicuous stars.


Perseus is the name of the constellation located in the northern portion of the sky. Its name honors the famous Greek demigod who defeated Medusa, the gorgon who petrified anyone who looked into her eyes. He was the son of the Greek God Zeus (whose Roman form is Jupiter). It is a popular boy name, and you can shorten it to Percy.



Leo is the name of a constellation containing clusters of shiny stars. This constellation was discovered quite early. The name Leo, meaning ‘lion’, was very popular in ancient Rome. Besides, it has its own astrological significance, being a zodiac sign. It is a popular boy name, but can also be used as a nickname for girls.


Sirius is an excellent name to bestow on your son. Also called the Dog Star, Sirius is the brightest star in the sky. So your boy will always be radiating and shining wherever he goes. It is also the name of one of the most popular and best-loved characters of the Harry Potter series, Sirius Black.


Vulcan is the name of the hypothetical planet whose existence was proposed by scientists way back in 1915. The name is rising rapidly in popularity. So don’t consider it if you are looking for some unique name for your son.

Vulcans are also really cool aliens from the Star Trek saga, the species to which our beloved Mr. Spock belongs. So there you go, you now have a sentimental attachment to the name as well.


Hercules was probably the mightiest warrior in all of Greek mythology. He was the son of sky God Zeus, and undertook a series of impossible tasks to prove himself, including the slaying of the infamous monster, the Hydra. Hercules is also the name of a constellation. The name is derived from the Greek word “Herakles (Ηρακλής)”, which means ‘hero’ or ‘warrior’.


Ophelia is the name of one of the moons of Uranus. It was named after a character in William Shakespeare’s play Hamlet. It is sure to make a unique name for your daughter. Besides, there are many great cinematic characters called Ophelia, so your daughter will have plenty of namesakes that you can choose from.



Venus is the second planet in our solar system, after Mercury. It is also the name of the Roman goddess of beauty, which is a perfectly apt name to name your daughter. It makes the name royal and feminine.


Phoebe was the outermost moon of Saturn for nearly a hundred years. Meaning ‘bright, radiant and prophetic,’ Phoebe was also the name of the Greek titan of the moon who was the mother of Leto and the grandmother of twins Apollo and Artemis in Greek mythology. The name also shares a connection with one of the most famous sitcoms of all times, Friends, as one of its central characters was named Phoebe Buffay (and she was amazing).


Calypso is the name of a moon of Saturn. It is also the name of a character in Greek mythology. Calypso was the name of a nymph who lived on the Greek island of Ogygia. She is said to have detained the hero Odysseus on her island for seven years during the events of the Odyssey. She is the daughter of Greek hero Hercules.


Cosmos means the entire physical universe. So it’s a perfect option for your baby, who means ‘the world’ to you. The name has been popularized by some television shows. Remember Seinfeld?


Andromeda is a galaxy named after a Greek mythological princess. Legend has it that she was a beautiful princess who was offered as a sacrifice to the monster Cetus to appease the anger of the Gods. Of course, she was saved by Perseus, who killed Cetus, but that’s a different story.

The name means ‘ruler of man’. Being named after an entire galaxy, you can be assured that your little one will be at the center of the world.



Cassiopeia is the name of a constellation. It is named after the Greek queen Cassiopeia, whose beauty was said to be unearthly and unrivalled. It would be the perfect name for your daughter, who is definitely the most beautiful maiden in your world.


Okay, this is a personal favourite. Bianca is the name of a small moon in Uranus. It is named after one of the fascinating characters in William Shakespeare’s play, Taming of the Shrew. It is the perfect pick for parents looking for a unique and beautiful name for their daughter.


The name Aurora comes from the natural phenomenon of Aurora Borealis, also known as the Northern Lights. It is one of the most beautiful sights the human eye can behold. Additionally, it is also the name of a well-loved Disney princess, making it a perfect fit for your daughter.


Luna is Latin for moon. This sweet, short and celestial baby name is also the moniker of one of Harry Potter’s companions in J.K. Rowling series. It is a genuinely sweet name to bestow upon your child.


Cordelia is the name of the inner moon of Uranus. The moon was named after Queen Cordelia, the youngest daughter of King Lear from Shakespeare’s play with the same name. The princess was noted for her never-ending loyalty to her father and steadfast truthfulness. It is a beautiful name to give your child.

These are some of the best space and star themed names you can give to your child. They are meaningful and beautiful and are bound to make your child stand out from the rest.
