For example, Gliese 581 g is not the sixth planet from its star (which we can't know for certain at this point anyway) but rather the sixth planet discovered in the system. It's actually the closest (we know of) to its star.

Just to ask, would the first planet in a binary system be named [Star-Classification] c? If not, then why do they skip "a"?

Stars and planets seem to be numbered in the same system with capital letters for stars and lowercase for planets, with "A" always going to the brightest object (which will by definition always be the star); only necessary to specify the "A" if there's more than one star though.

Real Life
  • If we ever find intelligent alien life, chances are high it will come from a star with one of these numbers, and it is certain that its planet will only have a letter at first. For example, Gliese 581-d and OGLE-2005-CLG-390L-b are two planets that may have Earth-like conditions conducive to life.

Does this even count when, you know, we have no access to that planet?

I deleted Coruscant as being an example of the trope, partly because of an ungodly amount of natter, but also because the "triple zero" seems to refer to the sector's location in space, not the actual planetary designation.
