Questions about naming a star in Gemini

Can I really name a star in Gemini?There are over 1,460 catalogued stars in Gemini available to name right now. You choose one, name it, and it’s recorded uniquely to you in the Caelum Star Registry.
Is this an official scientific name?No, and we’ll always be straight with you about that. Only the International Astronomical Union officially names stars. Caelum is a beautiful, heartfelt keepsake: your name is held in our registry and never given to anyone else.
When can I see Gemini in the sky?Gemini climbs highest in the evening around February, and is best placed for the northern hemisphere and tropics. Your star page even shows when it’s visible from your exact location tonight.
An honest keepsake. Caelum is a meaningful gift and a real star from published astronomical catalogues. But it is not an official IAU scientific designation. Only the International Astronomical Union officially names stars. We think the gift means more when it’s honest.
