How to use the star ID and coordinates lookup

Find the registration number printed on the certificate or confirmation email.
Enter the complete code in the lookup above. Registration numbers are more reliable than personal names because every code is unique.
Open the matching star to see its dedicated name, constellation, right ascension and declination.
Use the coordinates in the free Star Finder app or follow our guide to finding a star in the night sky.

If a code returns no match, check easily confused characters such as zero and the letter O, then confirm that the certificate belongs to the Star-Register partner network. Other private registries maintain separate databases, so their registration numbers may not appear here.

This is a private star-registry lookup, not a search of every star in scientific databases such as SIMBAD or Gaia. It searches exact Star-Register registration numbers. If you have coordinates or a scientific catalogue identifier instead, use those details in an astronomy database.

About the star register

This catalogue is the public, searchable record of every star named through Star-Register - currently 179,510 stars dedicated by people around the world. Each one is a real star with verified celestial coordinates, checked against established astronomical catalogues such as Hipparcos and Tycho-2, so it can actually be located in the night sky and viewed through a telescope at an observatory near you. The register spans all 94 constellations visible from Earth, with the most-named including Ursa Major (8,733) · Draco (8,213) · Cygnus (8,073) · Cassiopeia (7,442) · Leo (6,892) · Sagittarius (6,623).

What a registration number is

When a star is named, it receives a permanent registration number - a short code like F1B7201ED that is unique to that dedication and never expires. Enter it in the search box above to pull up the star's name, constellation and coordinates at any time, or open its dedicated page to share it. It is the reliable way to find a specific star, because a registration number is unique even when two people choose similar names.

Named stars vs. scientific catalogues

Professional astronomy identifies stars by catalogue designations (HIP, HD, Tycho numbers) rather than names. A Star-Register dedication is a symbolic, commemorative naming layered on top of a real, catalogued star - a meaningful gift, not a scientific renaming. To compare those catalogue identifiers with established proper names and stellar science, explore our researched guides to 100 star names and meanings. The underlying coordinates are genuine, which is why you can point a telescope at your star or follow the augmented-reality Star Finder app straight to it.

Good to know

Star catalogue questions, answered

How do I look up a star by its registration number?

Type the registration number - for example F1B7201ED - into the search box above the table. The catalogue matches it exactly and opens that star's sky view, showing its name, constellation and celestial coordinates. The registration number is printed on your certificate and never changes.

How many stars are in the register?

The catalogue currently holds 179,510 named stars spread across 94 constellations, making it one of the oldest and largest online star-name registers. New dedications appear here with a unique registration ID within minutes of naming.

What information is stored for each star?

Every entry records the star's dedicated name, its constellation, its exact celestial coordinates (Right Ascension and Declination), and a permanent registration number. Those coordinates let you - or an observatory - point a telescope straight at your star.

Are these star names official or recognised by astronomers?

Star-Register is a private commemorative register: your dedication is a genuine, permanent entry with a unique ID that never expires. It is a symbolic naming, not an official scientific designation - no star registry, ours included, is recognised by NASA or the International Astronomical Union, which do not sell or assign star names.

Can two stars have the same name?

No. Every new name is checked against the register for duplicates before it is recorded, so each dedication stays unique. The registration number is unique regardless of the chosen name.

How do I find my star in the night sky?

Open your star from the catalogue to see its sky view and coordinates, then enter your registration number in the free Star Finder app to point your phone at the exact spot using augmented reality. You can also take the coordinates to any observatory.

Not in the catalogue yet?

Name your own star and it will appear here with a unique registration ID within minutes.
