I guess this is just a lame visual shorthand for "the planet is habitable"
But one can just write that they're habitable in the description (or assume that if you're a viewer, use your damn imagination, there's infinitely more than 9 planets in the universe)
This seems like less of a stretch to assume than "a bunch of Earth copies exists here because the giantess has just pulled them from parallel worlds"
