Celestial Object Renaming Engine

Every star has burned long before
men have walked the earth.

Yet we give them the most foolish of names.

The Problem

The IAU names the Stars.
But sometimes they get it wrong.

The International Astronomical Union is the sole legitimate authority on the naming of celestial objects. We respect that authority enough to catalog every name they have ever approved, (all 650+ of them) in this database, with full attribution and permanent records.

Many stars have been given venerable and honorable names, like Arcturus and Copernicus, named after their characteristics or after a famous Astronomist or Scientist. This is completely acceptable for a Star. But what has been done recently is not this. That is exactly why we will say this plainly: some of the recent names given to Stars are an embarrassment to the objects they label.

A star has been burning since before the first man has existed on this planet. A Star is the means by which life survives on this or any planet. It has been present at every moment of cosmic history we know about. Yet the organization tasked with naming it decided, in the year 2024, to call one of them Dust-Ball.

"We want to be clear. We are not against the IAU. We catalog their names and always will. We are against the idea that a star deserves the same energy as naming a goldfish."

We understand how it happens. The WGSN accepts name proposals from member states and national societies. Some names are genuinely beautiful. Betelgeuse, Aldebaran, Diadem, and many others, ancient names carried forward across millennia of stargazing cultures, each one a thread connecting us to the people who lay on their backs in the dark and looked up and wondered. But then the IAU goes and names one of these beautiful stars Flying Saucer.

The list goes on. And on. And on.

How can this be? Who approves this? Who sits at their desk and thinks, "Oh yes, I vote for that name." How is this right? These names are officially approved. Forever named. Placed in the permanent record.

This nonsense has to stop. The nations must protest this. No, the entire world must protest this. For us, our protest comes in the form of a new engine, an engine we call CORE. CORE stands for Celestial Object Renaming Engine. An engine built solely to give each star (at least in our galaxy) a proper and beautiful name. CORE has already named over 55M+ objects, stars and galaxies, and it can do so much more. We are fully aware that the IAU will never use our engine. But we don't care. CORE is not just a protest. It is an answer.

These are real Star names the IAU Approved.
They are Permanent.

Each name below was approved by the IAU Working Group on Star Names and will appear in the permanent astronomical record for as long as humanity keeps records. See the names below to our utter shame.

How to Use CORE

Four ways the public
can engage with this engine

✦
Gift a star
When you gift a star through TheStarDB, CORE automatically assigns it a name if the IAU has not named it already. That name appears on the certificate, on the star's permanent page, and is rendered live in STEN every time the QR code is scanned. The IAU has officially named 650 stars out of an estimated 100 billion in our galaxy alone. There are 16 million cataloged in this database. Every single one of them deserves a name with weight behind it. CORE gives them that.
⌕
Look up any star
Use the CORE search engine below on this page to find any star's CORE name by its IAU proper name, HIP designation, or Gaia catalog ID. The engine returns the CORE name alongside its reason: the archetype, the spectral class, the physical properties that shaped the choice. Every name is deterministic. Search the same star a thousand times and you will get the same name. It is not random. It is not arbitrary. It is derived from what the star actually is.
</>
Use the API
CORE is a public engine. No account, no API key, no sign-up. GET https://api.core.thestardb.org/search?q=Vega&table=stars returns the scientific name, CORE given name, and the full name reason for any object in the catalog. Query stars, galaxies, pulsars, neutron stars, and all 22 object types freely. Requests are rate-limited per IP to prevent abuse. Normal use will never hit the limit. See the CORE specification for the full engine reference.
✉
Make your voice heard
The IAU WGSN accepts public feedback and proposals. Write to your national astronomical society. Send a letter directly to the IAU. Call out the names by name: Dust-Ball, Lich, Speedy Mic, Flying Saucer. Post about them. These names will be in the permanent record long after every person alive today is gone. That is not a small thing. The only way this changes is if enough people say, out loud and in writing, that it is not acceptable. Share this page. Start the conversation. History is still being written, and right now it is being written badly.
When to Use CORE

An honest answer about
when this matters

CORE is not a replacement for the IAU catalog. It is a supplement, and an editorial statement. Here is when it is and is not the right tool.

Use CORE when…
  • A star has no IAU name and deserves one
  • You are gifting a star and want a name with weight
  • You are writing fiction, narrative, or creative work
  • You want to understand a star's character beyond its catalog designation
  • You are building an application and want names with meaning
Stick to IAU / catalog when…
  • You are writing scientific papers or peer review
  • The star already has an IAU-approved proper name
  • You need unambiguous cross-referencing between databases
  • Precision matters more than character
The CORE Philosophy

What every name
is built to do

A name is not a description. When you name a child, you are not cataloging their weight. You are saying: this one is known. A star deserves nothing less.

Principle I
Names are permanent
Once assigned, a CORE name is linked to catalog coordinates and physical data. It is not owned by any institution that might later change its mind.
Principle II
Names reflect the object
Spectral class, temperature, mass, distance, and evolutionary stage are inputs to the name. A red supergiant does not receive the name of a white dwarf.
Principle III
No two names alike
Across 16 million stars in this database, every CORE name is unique. No star shares its name with another.
Principle IV
IAU names always win
Every official IAU name takes precedence. CORE fills what IAU left unnamed, which is most of the sky.
IAU Name vs. CORE Name

See the difference for yourself

Type any IAU-approved star name, or try one of the examples below, and see what CORE would have named the same object instead.

Try: Vega · Sirius · Betelgeuse · Polaris · Antares

TheStarDB

Your star is already named.
Make it mean something.

Every star gift through TheStarDB carries a CORE name when the IAU hasn't named it. The name is on the certificate, the permanent page, and rendered live in STEN every time someone scans the code.
