When I was pregnant with my daughter, my partner suggested Luna. “It’s simple, it means moon, and she can shorten it or keep it as is,” he said. But then I panicked — would people take a space name seriously? Would she spend her teenage years resenting it? I did what any ESL teacher would do: I researched the etymology. Luna is the Latin word for moon, used for over 2,000 years. It’s grounded. It’s *real*. And suddenly, giving her a space name felt like giving her a piece of the universe — not a gimmick.
I’ve explored space-inspired baby names — from the classical (Mercury, Mars, Venus) to the modern (Orion, Cosmo, Nova) to the fictional (Leia, Lyra, Kael). You’ll find where each name comes from, what it means, how to pronounce it, and how it lands in English-speaking cultures. Whether you’re drawn to mythology, astronomy, or the sheer romance of celestial names, You’ll help you choose one that feels right — and will still make sense when your child is filling out a job application.
Key Takeaways
- Classical planet names are 2,000+ years old — Mercury, Venus, Mars, Jupiter all come from Roman mythology and are grounded in history.
- Constellation names are even older — Orion, Cassiopeia, Andromeda come from ancient Greek mythology, used for navigation for millennia.
- Astronomer and spacecraft names are trendy — Armstrong, Kepler, Juno, Curiosity draw from real space exploration.
- Space names work for both genders now — Luna, Aurora, Lyra are feminine; Orion, Atlas, Cosmo can be masculine or unisex.
- Fictional space names are risky — Leia (Star Wars) is established enough now, but Anakin or Katniss may date quickly or feel too tied to one cultural moment.
Classical Planet Names: Ancient Roots
The planets visible to the naked eye have been named for millennia. The ancient Greeks and Romans named them after gods and goddesses, and those names have stuck for over 2,000 years. As baby names, they’re not trendy — they’re classical.
The Eight Planets as Names
| Planet name | Roman god | Meaning / domain | As a baby name? | Pronunciation |
|---|---|---|---|---|
| Mercury | Messenger god | Communication, travel, commerce | Rare but literary (Mercury Prize, mythology fans) | /ˈmɜːr.kjə.ri/ |
| Venus | Goddess of love | Love, beauty, desire | Occasionally used; feels romantic and strong | /ˈviː.nəs/ |
| Mars | God of war | Conflict, courage, aggression | Uncommon as a given name; used occasionally (usually for boys) | /mɑːrz/ |
| Jupiter | King of the gods | Power, authority, expansion | Very rare; feels grandiose | /ˈdʒuː.pɪ.tər/ |
| Saturn | God of agriculture | Time, discipline, limitation | Rare; feels unusual but not impossible | /ˈsæt.ɜːrn/ |
| Uranus | God of the sky | Sky, breath, infinity | Very rare as a given name (pronunciation awkwardness) | /ˈjʊr.ə.nəs/ or /juːˈreɪ.nəs/ |
| Neptune | God of the sea | Water, depth, mystery | Rare but used (especially as a middle name) | /ˈnɛp.tjuːn/ |
Example 1: Venus is occasionally used as a given name, particularly for girls. It carries centuries of poetic association (Aphrodite, Botticelli, Shakespeare) without feeling like a character name.
Example 2: Mars as a name is rare, but it’s used. It has the quality of being short, strong, and undeniably masculine — though some parents worry about the “god of war” association.
A note on Pluto: Pluto was classified as a “dwarf planet” in 2006, so it’s no longer counted among the eight classical planets. However, Pluto was named for the Roman god of the underworld (not Disney’s dog), and the name does appear occasionally in popular culture and baby-naming blogs. Understand that context before using it.
Constellation Names: Mythology and Navigation
Constellations have been used for navigation and storytelling for over 5,000 years. They draw from Greek, Roman, and Middle Eastern mythology. As names, they feel literary and cosmic without being too trendy.
The Major Constellations
| Constellation | Mythological figure / meaning | Visibility / fame | As a name | Pronunciation |
|---|---|---|---|---|
| Orion | Hunter from Greek mythology; said to be the most beautiful constellation | Visible in both hemispheres; very well known | Used occasionally for boys; strong, literary feel | /ɔːˈraɪ.ən/ |
| Cassiopeia | Vain queen of Aethiopia (ancient North Africa) | Circumpolar (always visible from Northern Hemisphere) | Used occasionally for girls; romantic, fantasy-literature feel | /ˌkæs.i.əˈpiː.ə/ |
| Andromeda | Princess chained to a rock as punishment; rescued by Perseus | Home of the Andromeda Galaxy; well-known myth | Used for girls; mythological, somewhat long | /ænˈdrɒm.ə.də/ |
| Leo | The lion; killed by Hercules in Greek mythology | Major constellation; zodiac sign | Very popular for boys; short, strong, timeless | /ˈliː.oʊ/ |
| Lyra | Lyre of Orpheus; symbol of music and poetry | Small but brilliant constellation | Used for girls; soft, musical feel (also familiar from “His Dark Materials”) | /ˈlɪr.ə/ |
| Cygnus | Swan; represents multiple swans from mythology | Visible in summer sky (Northern Hemisphere) | Rare as a given name; feels astronomical, not quite “baby-name-y” | /ˈsɪg.nəs/ |
Example: Leo is one of the most successful constellation names as a given name. It’s short, easy to spell, easy to pronounce, it has the mythology behind it, and it’s also the zodiac sign — so people don’t question it. A boy named Leo can be “just Leo” in a classroom and nobody blinks.
Modern Space Names: Astronomers, Missions, and Spacecraft
These names draw from real space exploration. They’re newer, trendier, and often honour scientists and astronauts. They feel contemporary in a way that classical mythology doesn’t.
Astronomer and Astronaut Names
- Armstrong (Neil Armstrong, first man on the moon)
- Glenn (John Glenn, first American to orbit Earth)
- Shepard (Alan Shepard, first American in space)
- Ride (Sally Ride, first American woman in space)
- Kepler (Johannes Kepler, discovered laws of planetary motion)
- Galileo (Galilei, first to use telescope for astronomy)
Example 1: Armstrong is occasionally used as a first name or middle name, honouring Neil Armstrong’s achievement without being *too* on-the-nose about it.
Example 2: Kepler is trending upward, especially among STEM-minded parents who want a name that feels scientific but also has a soft quality.
Spacecraft and Mission Names
| Spacecraft / mission name | What it explored | As a baby name | Pronunciation |
|---|---|---|---|
| Cassini | Saturn and its moons (2004–2017 mission) | Growing; sounds classical (from Giovanni Cassini, astronomer) | /kæˈsiː.ni/ |
| Juno | Jupiter (ongoing mission) | Used occasionally; short, strong, mythological (Roman queen of heaven) | /ˈdʒuː.noʊ/ |
| Curiosity | Mars rover (ongoing) | Rare; more a virtue name than a space name, though the rover is famous | /kjuːˈrɪɒs.ə.ti/ |
Astronomy-Inspired Trend Names: Modern and Unisex
These are newer names inspired by space and astronomy concepts rather than directly taken from constellations or planets. They’re trendy, often unisex, and designed to feel modern while retaining cosmic meaning.
| Name | Meaning / origin | Gender / popularity | Pronunciation |
|---|---|---|---|
| Luna | Latin for moon; also goddess of the moon | Feminine; increasingly popular; also unisex in some contexts | /ˈluː.nə/ |
| Aurora | Roman goddess of dawn; also the aurora borealis (northern lights) | Feminine; classic and trending; used in Sleeping Beauty | /ɔːˈrɔːr.ə/ |
| Nova | Latin: “new” star; an explosion event in astronomy | Unisex; trendy; modern feel with scientific meaning | /ˈnoʊ.və/ |
| Stella | Latin for star; classic, timeless | Feminine; literary (Streetcar Named Desire, etc.) | /ˈstɛl.ə/ |
| Cosmo / Cosima | Greek: “order” or “universe”; implies cosmic understanding | Cosmo masculine or unisex; Cosima feminine; both trendy | /ˈkɒz.moʊ/ /ˈkɒz.i.mə/ |
| Atlas | Greek Titan who held the sky; also the name of maps | Masculine or unisex; literary, strong | /ˈæt.ləs/ |
| Vega | Brightest star in Lyra constellation | Unisex; short, punchy, scientific | /ˈveɪ.ɡə/ |
Example 1: Luna has become one of the most popular space-inspired names for girls in the last ten years. It’s short, easy to spell, easy to pronounce, and the moon is universally understood — Luna works in English, Spanish, Italian, Portuguese, and many other languages.
Example 2: Nova is unisex, trendy, and has a genuine astronomical meaning (a “new” star, or a stellar explosion event). It’s modern without feeling made-up.
Fictional Space Names: Books, Films, Games
Fictional space names come from sci-fi literature, films, and games. Some have entered mainstream culture; others remain niche. Use caution — a fictional name can feel trendy now but dated in ten years.
Literary Space Names
- Lyra (from “His Dark Materials” by Philip Pullman; now also real constellation)
- Ender (from “Ender’s Game” by Orson Scott Card; rare as a given name)
- Arrakis (from “Dune” — a planet name; very rarely used for humans)
- Katniss (from “The Hunger Games” — cultural moment, may feel dated)
Film and TV Space Names
- Leia (Princess Leia from “Star Wars”; now mainstream enough to work)
- Anakin (from “Star Wars”; feels very tied to one character)
- Rey (from recent “Star Wars”; short, modern, works without the sci-fi reference)
- Dune (from “Dune” films; very rare as a given name)
Fictional name caution: If you’re choosing a fictional space name, ask yourself: would this still feel good if nobody remembered the film or book it came from? Lyra works because it’s also a real constellation. Leia works because few people now remember Star Wars as obscure. Anakin feels riskier — it’s very tied to one character, and one set of films that may feel dated in 20 years.
Pronunciation and Spelling: Why It Matters
| Name | Common mispronunciation | Correct pronunciation | Tip |
|---|---|---|---|
| Cassiopeia | “Cas-ee-oh-PAY-uh” or “Cas-ee-oh-PEE-uh” | /ˌkæs.i.əˈpiː.ə/ (KAS-ee-uh-PEE-uh) | Think “Cas-see-uh” + “PEE-uh” at the end |
| Orion | “OR-ee-un” (neutral); correct is slightly different | /ɔːˈraɪ.ən/ (or-RY-un) | Stress on the second syllable |
| Andromeda | “An-DROM-uh-duh” (neutral pronunciation exists) | /ænˈdrɒm.ə.də/ (an-DROM-uh-duh) | Four syllables; stress on second. Don’t collapse it to “Andy.” |
| Lyra | “LEER-uh” (neutral; acceptable) | /ˈlɪr.ə/ (LEER-uh) or /ˈlaɪ.rə/ (LY-ruh) | Both pronunciations are used; pick one and stick with it |
| Cosmo | “CAWS-mow” (neutral) | /ˈkɒz.moʊ/ (KOZ-moe) | Rhymes with “Gizmo” |
Common Mistakes When Using Space Names
✗ Incorrect: “My daughter is Luna — like the Disney character.”
✓ Correct: “My daughter is Luna — the Latin word for moon.”
Why: Luna existed for 2,000 years before Disney made a film. Grounding the name in its real meaning gives it more weight and history.
✗ Incorrect: “I named my son Orion because it sounds cool.”
✓ Correct: “I named my son Orion after the constellation — a hunter from Greek mythology, and one of the brightest constellations in the sky.”
Why: Understanding the etymology and mythology behind the name makes it feel substantive, not trendy.
✗ Incorrect: “Space names are weird — nobody uses them.”
✓ Correct: “Some space names like Luna and Leo are mainstream now; others like Cassiopeia or Juno are still rare.”
Why: Trendiness changes. Luna, Aurora, and Leo are solidly mainstream. Cassiopeia and Orion are rare but established. Anakin or Katniss are riskier.
Sample Dialogue: Choosing a Space Name
Alex: We’re having a baby and thinking about space names. My partner likes Luna.
Jamie: Luna is beautiful — short, easy to spell, and it works in multiple languages.
Alex: But is it too trendy? Will it feel dated in twenty years?
Jamie: Luna has been the Latin word for moon for 2,000 years. It’s not going away. Trendy is OK if the name has real history behind it.
Alex: What about Orion? That’s more unique.
Jamie: Also beautiful — but longer. Orion might get shortened to “O” or “Ory” in casual contexts. Luna stays Luna. It depends on what you prefer.

Frequently Asked Questions
Are space names too trendy or will they last?
Names like Luna, Aurora, and Leo have deep historical and mythological roots — they’re not trendy in the “flash in the pan” sense. However, very recent fictional names (Katniss, Anakin) carry more risk of feeling dated. Choose names with real history (mythology, astronomy) over purely fictional ones, and you’ll be fine.
Do space names work for both boys and girls?
Many do now. Luna, Aurora, Stella, and Lyra are traditionally feminine. Orion, Leo, and Atlas are traditionally masculine. Nova, Cosmo, and Vega are unisex. The trend is toward more unisex space names, so gender flexibility is increasing.
Is it OK to name my child after a fictional space character?
Yes, if the fictional character comes from a deeply established cultural work (Star Wars’ Leia is mainstream now). Be cautious with very recent characters (Katniss, Anakin) because they’re heavily tied to current pop culture. If your child is the only Katniss in her school now, she might regret it when the Hunger Games films feel dated.
How do I make sure I pronounce space names correctly?
Listen to audio pronunciation guides (Forvo, Oxford Dictionary, YouTube) for constellations and classical names. For fictional names, check fan communities or official sources. For your own child, you get to decide — but consider: will others be able to pronounce it? Will they be able to spell it? Luna, Leo, and Nova have clear pronunciations; Cassiopeia and Andromeda are harder.
Are there any space names that are actually difficult to live with?
Names that are very long (Andromeda) or feel very tied to fiction (Anakin) can be challenging. Also avoid names that have other common meanings (Mars = the candy bar, Saturn = the car). A child named Mars or Saturn might hear jokes about those brands forever. Luna, Orion, Leo, and Nova are generally safe — easy to spell, easy to pronounce, meaningful, and not too trendy.
Can I use a space name as a middle name instead of a first name?
Absolutely — this is a great middle ground. Luna Marie, Leo James, or Cassiopeia Rose gives you the poetry of the space name without the everyday challenge of living with something very unusual. Many parents use this approach successfully.
