The IAU gives official scientific names to craters, but it has only bothered with craters that have "scientific significance." The science-funding platform Uwingu has launched a campaign to come up with popular names for the remaining craters. For as little as $5, a member of the public can name one of the craters on Uwingu's map, with the proceeds going to fund space science and education.
This caused the IAU to issue a statement condemning such crowdsourcing efforts. The IAU pointed out that it did allow the public to vote on names for two of Pluto's moons, in the past. In that case, however, the IAU rejected the winning name (Vulcan)."
