Top 10 galaxy baby names
These 10 space baby names are the most common names and trendsetters that we predict we will be seeing a lot more of in 2023 and beyond.
1. Nova – A powerful astronomy name, Nova is the name given to bright stars that appear suddenly in the sky and release powerful energy. We’ve seen the name Nova on a lot of baby name lists lately and expect it to continue to soar.
2. Luna – The original moon baby name, Luna means “moon” and is one of the most-searched baby names in the world.
3. Phoebe – Another moon name that remains a popular choice, Phoebe is one of Saturn’s moons.
4. Hallie/Halle/Halley – Referencing the comet, Halley remains quite unique but the alternative spellings, such as Hallie and Halle are quite popular.
5. Stella – There are plenty of star baby names but Stella is perhaps the most well-known one. Stella means, you guessed it, “star”.
6. Elio – Watch Elio rise! This name means “the sun” but it’s also the name of the newest Disney-Pixar hero.
7. Cosmo – Of all the popular space baby names, this one is probably the one out of this world, but we predict big things for Cosmo, especially after Scarlett Johansson used it for her son.
8. Phoenix – Speaking of celebrities and space baby names, Phoenix is another one – Paris Hilton just announced this is her newborn son’s name. Phoenix is a mythological animal as well as a city in America, but it’s also a constellation.
9. Lyra – Lyra is a constellation. It contains the star Vega and is one of our top picks for trending four-letter names. Fun fact: Ed Sheeran named his daughter Lyra.
10. Leo – Leo is currently #6 on the list of most popular baby names in Australia and it’s easy to see why. This short and sweet name ticks a lot of baby name boxes. It’s powerful, punchy and also happens to be the same as a constellation.
