@SeeyaTheFurry i can confirm this too

i was initially surprised by the Tau Ceti system with the weird designations but then i learned the way it works and now i sometimes use it in my own systems too
one thing to also note is that "A" (capital) is used for the star itself, and the first discovered exoplanet would be "b" (lowercase) and then the following ones too
with multi-star systems it's a bit different, for example Alpha Centauri has the two main "A" and "B" stars (there's also Proxima as "C" but we'll ignore it for now since it's small and far away enough to not have a major effect on the entire trinary system afaik), in that case the exoplanet designations remain the same, so you can have something like "Alpha Centauri Bb" (is actually a hypothetical planet irl) while circumbinary orbits (around both stars, i.e. orbit center is the stars' barycenter) are usually "(AB) b" or similar from what i've seen

can you source the info @SeeyaTheFurry?

@Hyperant Exoplanet alphabetical naming is based on the order of discovery, not the actual orbital structure of the system

@Hyperant Im using this website to see exoplanets and it dosent list Tau Ceti B, it also doesnt appear in Space Engine so idk.

How is it Tau Ceti "H" if it is the second innermost planet? Shouldn't it be "B"?
