Star naming is the tradition of dedicating a real star in the night sky to a person or a memory. At The Starmint, you pick a real catalogued star (by constellation, zodiac sign, viewing location, or at random), give it a name, and we record the registration permanently on the Polygon blockchain, a public ledger. Your star is real, its coordinates are real, and the record is permanent.

Yes. Each star can be registered with The Starmint only once, so the gift is one of a kind: a real star in the night sky, named for someone, with a personalized certificate and a permanent record on the blockchain. It suits birthdays, anniversaries, memorials, new babies and Valentine's Day, and it lasts.

Yes. Every registration is recorded on the Polygon blockchain, a public ledger maintained by thousands of independent computers worldwide. No one can alter or delete the record, including us, and it does not depend on our company or our servers. To see yours, open your star from My Stars and select View on Blockchain. That is the difference from registries that keep names in a private company database.

The International Astronomical Union (IAU) assigns scientific star names for research purposes, and that process is closed to the public by design. No private registry anywhere can offer an IAU name. The Starmint creates personal dedications: a permanent record on the Polygon blockchain that is independently verifiable by anyone. For a gift or a memorial, that record is what matters.

You receive a personalized digital certificate showing your star's name, its catalogue identifier and its coordinates, with the option to add a date and a personal message. The certificate is in your Starmint account once your star is registered, and the registration is recorded permanently on the public blockchain. Printed keepsakes from our gift shop are made to order and shipped separately.

Yes. You can name a star for anyone, including someone who has passed away. The registration is permanent, and you can add a personal message of up to 570 characters to the certificate: a name, dates, or a few words about them.

Your certificate lists your star's catalogue identifier (for example, HD 131491) along with its right ascension and declination coordinates. Open Stellarium Web (stellarium-web.org), a free planetarium that runs in any web browser, and type the identifier into the search box. It centres the sky map on your star and shows how bright it is, so you know whether it is visible to the naked eye or needs binoculars. The star appears under its catalogue name; the name you chose is held in your Starmint registration.

Star Registration is $18. That includes your personalized digital certificate and the permanent blockchain record of your star's name. Printed keepsakes from our gift shop are priced separately.

Yes. We donate 20% of star registration fees to The Space Prize Foundation, a charity that empowers young women to take part in the growing space economy.
