Zoozve

Radiolab co-host Latif Nasser was putting his child to sleep one day when he noticed a poster of the solar system on the wall. It showed that Venus had a moon called Zoozve. When he looked it up, the internet told him that Venus did not have a moon. And searching “Zoozve” gave him a bunch of Czech results about zoos. This moment sets Latif off on a curiosity odyssey. What is the mystery behind this moon? Turns out, it’s both a moon and not a moon. And we get to name one. 

And now that you know all about quasi-moons, we have some fun news! Radiolab, along with the official governing bodies of space, want YOU to pick your favorite name for one of Earth’s newly discovered quasi-moons. Go to radiolab.org/quasi-moon to vote for the finalists. The winner will be chosen soon, so go help name a MOON!
