When you place an order with NamedLight, a star is selected and permanently assigned to your registration within seconds. But the pool that star comes from isn't random — it's the result of a specific set of decisions about which stars belong in a naming registry and which ones don't. Here's how we think about it.
It Starts With the HYG Stellar Database
Every star available through NamedLight comes from the HYG Stellar Database — a catalog of roughly 119,000 real stars compiled from three authoritative astronomical sources: the Hipparcos satellite catalog, the Yale Bright Star Catalog, and the Gliese Catalog of Nearby Stars. Each entry includes verified coordinates, a measured brightness, a spectral classification, and a calculated distance from Earth.
This is the foundation. Every star in our registry is a real, documented astronomical object — not a generated placeholder or an arbitrary coordinate.
Named Stars Are Excluded
Stars that already carry a proper name are removed from the available pool entirely. Sirius, Vega, Polaris, Betelgeuse, Arcturus — stars like these belong to shared astronomical heritage. Assigning them to individual registrations wouldn't be appropriate, and it would be misleading to imply otherwise.
Only unnamed catalogued stars are available to name through NamedLight. These are real, well-documented stars that have been measured and tracked for decades without ever having a human name attached to them. There are tens of thousands of them.
Brightness Determines the Tier
Star brightness is measured on the astronomical magnitude scale — a system where lower numbers mean brighter stars. We use that scale to define three tiers, each corresponding to a different brightness range in the catalog.
Bright tier stars fall between magnitude 7.0 and 8.0 — just below naked-eye visibility but well within binocular range. Brilliant tier stars fall between magnitude 5.0 and 7.0, at or near the threshold of what the naked eye can detect on a clear night. Supernova tier stars are magnitude 5.0 or brighter — the most luminous unnamed stars in the catalog, assigned starting from the brightest available.
The tiers exist so that the star you receive actually corresponds to what you paid for. When you choose the Supernova package, you get a genuinely brighter star — that's built into the assignment logic, not a marketing description.
The 30 Curated Constellations
Not every constellation in the sky makes a meaningful choice for a registry. We maintain a curated list of 30 constellations that are recognizable, well-distributed across both hemispheres, and rich enough in unnamed catalogued stars to support ongoing assignments. Familiar names like Orion, Leo, Cassiopeia, and Lyra sit alongside less well-known but equally rewarding constellations like Aquila, Cepheus, and Corona Borealis.
If you request a specific constellation, the system searches within that constellation first. If a match at your tier isn't available there, it expands the search — first to the hemisphere you selected, then to the general pool. A star is always assigned.
Each Star Is Assigned Once
The moment a star is assigned to a registration, it's permanently marked in our system and removed from the available pool. It can never be assigned again. This isn't a policy we enforce manually — it's built into the assignment logic at the database level. The same star cannot appear in two registrations.
This is the part of the process that matters most for the integrity of the registry. A named star that belongs to someone else would undermine the whole point of naming one. Every assignment is permanent and unique.
Why It's Set Up This Way
The goal was to build a registry that could be taken seriously — not because commercial star naming is scientifically recognized (it isn't, and we say so clearly), but because the star underneath the name should be real, the data should be accurate, and the registration should mean something. That means real sources, real exclusions, real uniqueness, and real brightness tiers.
The name is symbolic. Everything supporting it is genuine.
