Your name in the sky vs ‘name a star’: what’s official and what’s marketing
Clear differences between official catalogs (IAU/USGS, MPC, NASA/JPL) and commercial ‘star naming’ services.
If you’ve ever seen a website that lets you “name a star”, you’ve also seen why this can be confusing. Let’s separate official astronomical naming from marketing products.
Official naming: what is it?
In professional astronomy, names are tied to catalogs and standards:
- Planetary surface features: IAU/USGS nomenclature (craters, mountains, valleys…)
- Minor planets (asteroids): naming and numbering overseen by the Minor Planet Center (MPC), with data available through NASA/JPL services such as SBDB
- Stars: most stars are referenced by catalog identifiers (HD, HIP, Gaia…) rather than a unique “purchase name”
What ‘name a star’ services actually do
These services usually create a private registry. You get a certificate, but:
- It does not update scientific databases.
- It does not make the name “official” in astronomy.
- The same star may be “named” multiple times by different vendors.
What this project does instead
Your name in the sky only:
- searches public, official sources, and
- shows matches (exact or approximate) with a link to verify.
That’s why we always show an “Important” notice on the page.
Practical check-list (before you trust a name)
- Does it link to an official source (IAU/USGS, MPC, NASA/JPL)?
- Does it provide coordinates or a catalog ID?
- Can you independently verify it?
Keyword focus: “is name a star official”, “IAU official naming”, “asteroid naming rules”.
