[marvel]how many planets does galactus eat in a year?
gpt
Normally one every three to four weeks. Particularly rich planets could sometimes hold him for over a month. After Annihilation, however, he was going through multiple planets in a single week, due to how much he'd been starved.

This might seem like a lot, but remember that Galactus roams the entire universe. It might take him centuries to get through all of the possible meals in a single cluster. By the time he's moved halfway across the universe, the systems he's visited have already died and reformed into new stars and planets.
